There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such
power modes are currently not supported by Zephyr.
To facilitate adding support for such class of power modes in the future
and to ensure the naming convention makes it clear that the currently
supported power modes stop the CPU this commit renames Low Power States
to Slep States and updates the documentation.

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

nRF52810 Flash and SRAM sizes do not have power-of-two values.
This commit reduces the amount of MPU regions reserved at boot
time to enforce basic permissions in Flash and SRAM memory. It
does this by selecting the next power-of-two size for the Flash

entire Flash and SRAM space each with a single MPU region, thus,
save two MPU regions to be used by the kernel/application.

This commit simplifies OS <-> Application interface controlling power
management. In the previous approach application-based PM required
overriding sys_suspend() and sys_resume() functions. As these functions
actually implemented power state change, in such case application
basically had to provide own implementation of all PM-related stuff,
which was not portable and hard to maintain.
This commit changes this scheme: The sys_suspend() and sys_resume()
are now system functions while the application could either use
built-in power management policies or provide its own. All details
of power mode switching are now handled by the OS.
Also, this commit cleans up the Kconfig options related to system-level
power management grouping them under common CONFIG_SYS_PM_ prefix.

A common driver is shared between stm32 chips, which was not the case
for stm32f3 series. As a consequence stm32f3 was not maintained
equally and was missing features such as flash layout or dts based
configuration.
Besides, drivers had some flows such as wrong bus clock and
missing HSI clock activation which lead to issues on boards not
using HSI as main clock.
As a consequence this commit moves stm32f3 series flash driver to
common stm32 flash drivers.

Refactor the imx rt code/data location config defaults such that we
default to on-chip memories at the soc level and override to external
memories at the board level. This means that we frequently override soc
defaults for evk boards, but it removes the assumption that all imx rt
boards (particularly non-evk boards) will have the same external
memories as evk boards.
The end result is that imx rt evk boards still have the same defaults as
before, but the way we get there is different.

The imx rt family of socs has several options for linking code and data

The number of warnings increased as we added more imx rt boards. Fix the
warnings by moving code and data location configs from the board level
to the soc level.
The default memories for all imx rt boards are unchanged. The
mimxrt10{20,50,60}_evk boards still default to hyperflash/qspi for code
and sdram for data. The mimxrt1064_evk board still defaults to ITCM for
code and DTCM for data because jlink does not yet support programming
internal flash.
