Changes affect introducing:
 - architecuture files (dtsi)
 - configuration of nrfx drivers
 - adaptation of inclusions based on chosen SoC
 - configuration of NFCT_PINS_AS_GPIOS depends on HAS_HW_NRF_NFCT.

2115099932 nordic: Update nrfx HAL function calls after switching to nrfx 2.0.0
Calls to nrfx HAL functions in various nRF platform related source
files are complemented with pointers to relevant peripherals.

Additionally, TIMER HAL functions that got renamed in nrfx 2.0.0 are
updated in the qemu_cortex_m0 board supporting code.

4f77c2ad53 kernel: rename z_arch_ to arch_
Promote the private z_arch_* namespace, which specifies
the interface between the core kernel and the
architecture code, to a new top-level namespace named
arch_*.

This allows our documentation generation to create
online documentation for this set of interfaces,
and this set of interfaces is worth treating in a
more formal way anyway.

2d7460482d headers: Refactor kernel and arch headers.
This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.

The refactoring strategy used in this commit is detailed in the issue

This commit introduces the following major changes:

1. Establish a clear boundary between private and public headers by
  removing "kernel/include" and "arch/*/include" from the global
  include paths. Ideally, only kernel/ and arch/*/ source files should
  reference the headers in these directories. If these headers must be
  used by a component, these include paths shall be manually added to
  the CMakeLists.txt file of the component. This is intended to
  discourage applications from including private kernel and arch
  headers either knowingly and unknowingly.

  - kernel/include/ (PRIVATE)
    This directory contains the private headers that provide private
   kernel definitions which should not be visible outside the kernel
   and arch source code. All public kernel definitions must be added
   to an appropriate header located under include/.

  - arch/*/include/ (PRIVATE)
    This directory contains the private headers that provide private
   architecture-specific definitions which should not be visible
   outside the arch and kernel source code. All public architecture-
   specific definitions must be added to an appropriate header located
   under include/arch/*/.

  - include/ AND include/sys/ (PUBLIC)
    This directory contains the public headers that provide public
   kernel definitions which can be referenced by both kernel and
   application code.

  - include/arch/*/ (PUBLIC)
    This directory contains the public headers that provide public
   architecture-specific definitions which can be referenced by both
   kernel and application code.

2. Split arch_interface.h into "kernel-to-arch interface" and "public
  arch interface" divisions.

  - kernel/include/kernel_arch_interface.h
    * provides private "kernel-to-arch interface" definition.
    * includes arch/*/include/kernel_arch_func.h to ensure that the
     interface function implementations are always available.
    * includes sys/arch_interface.h so that public arch interface
     definitions are automatically included when including this file.

  - arch/*/include/kernel_arch_func.h
    * provides architecture-specific "kernel-to-arch interface"
     implementation.
    * only the functions that will be used in kernel and arch source
     files are defined here.

  - include/sys/arch_interface.h
    * provides "public arch interface" definition.
    * includes include/arch/arch_inlines.h to ensure that the
     architecture-specific public inline interface function
     implementations are always available.

  - include/arch/arch_inlines.h
    * includes architecture-specific arch_inlines.h in
     include/arch/*/arch_inline.h.

  - include/arch/*/arch_inline.h
    * provides architecture-specific "public arch interface" inline
     function implementation.
    * supersedes include/sys/arch_inline.h.

3. Refactor kernel and the existing architecture implementations.

  - Remove circular dependency of kernel and arch headers. The
   following general rules should be observed:

    * Never include any private headers from public headers
    * Never include kernel_internal.h in kernel_arch_data.h
    * Always include kernel_arch_data.h from kernel_arch_func.h
    * Never include kernel.h from kernel_struct.h either directly or
     indirectly. Only add the kernel structures that must be referenced
     from public arch headers in this file.

  - Relocate syscall_handler.h to include/ so it can be used in the
   public code. This is necessary because many user-mode public codes
   reference the functions defined in this header.

  - Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
   necessary to provide architecture-specific thread definition for
   'struct k_thread' in kernel.h.

  - Remove any private header dependencies from public headers using
   the following methods:

    * If dependency is not required, simply omit
    * If dependency is required,
      - Relocate a portion of the required dependencies from the
       private header to an appropriate public header OR
      - Relocate the required private header to make it public.

This commit supersedes #20047, addresses #19666, and fixes #3056.

c24c463328 soc: nordic: Include <nrfx.h> instead of <nrf.h> from <soc.h>
This change is done so that there is no need to additionaly include
<nrfx.h> before <soc/nrfx_coredep.h> (what might be a bit surprising)
and so that <nrfx_config.h> doesn't need to be include separately for
nRF SoCs requiring a special mapping of peripheral accessing symbols.

This commit removes also no longer needed inclusions and updates
the hal_nordic module with required minor correction of nrfx_glue.h.

57c6cfc9cd nordic: Use hal/ in all inclusions of nrfx HAL header files

This commit adds basic support for nrf52811 in the arch SoC, dts
and nrfx folders.

The nRF52811 is a Bluetooth 5.1 Direction Finding SoC with comprehensive
protocol support.
The nRF52811 SoC is capable of the latest features of Bluetooth 5.1,
the most prominent being Direction Finding.

The radio in the nRF52811 SoC has comprehensive protocol capabilities,
including Bluetooth 5.1 Directing Finding, all Bluetooth 5 features,
802.15.4, Thread, Zigbee, ANT and 2.4 GHz proprietary.
It has 4 dBm TX power and has been optimized to offer the best RX
sensitivity of all SoCs in the nRF52 series.

da3f7feaf8 soc: arm: nordic_nrf: unrevert provide custom busy_wait implementations
This reverts commit bd24b31139.

While the test case failure described in #14186 is associated with the
cycle-based busy-wait implementation, that test is fragile, and fails
less frequently once the incongruence between ticks-per-second and the
32 KiHz RTC clock are resolved.  It also assumes that the system clock
is more stable than the infrastructure underlying the the busy-wait
implementation, which is not necessarily true.

The gross inaccuracies in the standard busy-wait on Nordic described in
issue #11626 justify restoring the custom solution.

As this applies to all Nordic devices, move the setting to the top-level
Kconfig.defconfig.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

Implementation taken from Nordic nrfx version 1.3.1 soc/nrfx_coredep.h,
modified to remove material from other series and to conform to Zephyr
coding standards.

Note that unlike standard k_busy_wait this is susceptible to
longer-than-intended delays due to the impact of interrupt handling.
