The JEDEC API defines the hardware page, sector, and block sizes.
Deprecate the Kconfig settings, remove the `erase-size-block` property,
and add `has-be32k` to indicate that 32K-byte erase is supported.
Rework the driver to use the constants instead of configured values.

Flash size calculation was don with assumption that flash page size
is always 1 KB and flash size was parameterized with such granularity.
This patch correct this bug.
Flash pages number under statistic can't be calculated via preprocessor
anymore - thus are parameterized via Kconfig.

An external project extending the Zephyr RTOS and its drivers may have
subsystems that must use its own specific driver(s) when active. One
example is the nRF5x NVMC that must be scheduled in between radio
operations. A subsystem may also be dependent on its own drivers for
security, real-time and/or because of hardware constrains.
In order to not introduce non-Zephyr specific code into the Zephyr tree,
an option is added to disable the in-tree drivers in Zephyr. Because
Kconfig does not support a good way of de-selecting other symbols, a
variable on the form `<DRIVER>_FORCE_ALT` is added as a
dependency for each `<DRIVER>`. For example, the out-of-tree subsystem
will select `FLASH_NRF_FORCE_ALT` to disable the in-tree driver. A
solution for issue #8181 would open up for a more general solution,
however #8181 requires significant effort.
Support for out-of-tree drivers is added to Nordic drivers for
clock_control, entropy and flash.
A generic solution for this is desired. Issue #14527 is tracking that
progress.

Disable the data cache before writing to Flash, in order to workaround
silicon errata 2.2.3: "Data cache might be corrupted during Flash memory
read-while-write operation". The data cache is conditionally re-enabled
once the write is completed.
This silicon bug has been encountered while stress testing the
implementation. Here are the events leading to the fault:
- Code is executing from Flash bank 1
- A write to Flash bank 2 is initiated
- The Cortex SysTick interrupt fires while waiting for Flash write
completion
In that case, the Flash controller will perform a read-while-write
operation in order to execute the ISR code. As the data cache is enabled
by default after reset, a corruption occurs due to the silicon bug,
leading to bizarre data bus faults or unaligned access faults inside
_timer_int_handler() or one of the functions called by the ISR.
Applying the workaround devised by ST fixes the problem.

The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

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
