c5839f834b kconfig: Remove assignments to CONFIG_<arch> syms and hide them
All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.

CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.

Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:

1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
   turn the CONFIG_<arch> symbols into invisible
   (promptless/nonconfigurable) symbols instead.

   Getting rid of the choice allows the symbols to be 'select'ed (choice
   symbols don't support 'select').

2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
   This makes sense since you know the architecture if you know the SoC.

   Put the select on the SOC_* symbol instead for boards that don't have
   a SOC_SERIES_*.

3. Remove all assignments to CONFIG_<arch> symbols. The assignments
   would generate errors now, since the symbols are promptless.

The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.

See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.

This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

d314253fbb soc: arm: xilinx_zynqmp: Relocate platform-specific initialisation.
This commit relocates the exception vector table address range
configuration routine that was previously implemented as part of
Cortex-R architecture reset function to SoC platform-specific
initialisation routine.

09ee834b4c soc: arm: xilinx_zynqmp: Refactor for multi-arch support.
The Xilinx ZynqMP SoC embeds both Cortex-R "RPU" and Cortex-A "APU"
cores.

Since the current Zephyr architecture cannot support AMP of Cortex-R
and Cortex-A within the same project, the RPU and APU should be
considered separate platforms and handled accordingly.

This commit re-purposes the SOC_XILINX_ZYNQMP symbol as a helper symbol
indicating that Xilinx ZynqMP SoC is used, and adds a new symbol,
SOC_XILINX_ZYNQMP_RPU, for specifying the actual build target platform.

When Cortex-A support is added in the future, SOC_XILINX_ZYNQMP_APU
symbol should be added and used to conditionally handle APU-specific
code.

For more details, refer to the issue #20217.

11d0f0a294 drivers: interrupt_controller: Refactor GIC configurations
The current GIC configuration scheme is designed to support only one
specific type and version of GIC (i.e. GIC-400 that implements the
GICv2 interface).

This commit adds a set of GIC version configuration symbols that can
be selected by the SoC configuration to specify which version of GIC
interface is implemented in the SoC.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

929dc717cf soc: arm: xilinx_zynqmp: Add qemu based SoC
This commit adds support for the Zynq UltraScale+ MPSoC as a qemu based
platform for Cortex-R based testing.  This SoC only supports an
interrupt controller and serial port for limited testing.
