This commit cleans up names of system power management functions by
assuring that:
- all functions start with 'sys_pm_' prefix
- API functions which should not be exposed to the user start with '_'
- name of the function hints at its purpose

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.

Since commit 0906a51dac, the driver
fails the test: tests/drivers/adc/adc_api. Some of the workflow
turns out to be incorrect (e.g. not doing dummy conversion after
getting out of deep power down, and not clearing interrupt status
bits). So take some time to overhaul the driver. Also rename
the driver to adc_intel_quark_se_c1000_ss because the inner
working of this driver is tied to Quark SE C1000 SoC.

On STM32F3 devices, a trick was required for normal use of registers.
This was actually an issue in flash registers defintions which should
be defined as volatile.

The iMX RT1060 and RT1064 have additional dedicated 512KB on-chip ram.
This OCRAM2 is mapped at 0x20200000, formerly OCRAM1 (flexram) mapping
which is moved to 0x20280000 in order to guarentee global OCRAM memory
continuity regardless OCRAM1 size configuration (256KB by default).
In default configuration, this gives 768KB (512+256) on-chip ram:
0x20200000 to 0x202BFFFF.
OCRAM2: 0x20200000 - 0x2027FFFF
OCRAM1(FlexRam): 0x2028FFFF - 0x202BFFFF
Add this memory region as a single node in the rt1060 device tree.
Note: MPU expects power of two memory region, in case of 768KB, let
the MPU configure 1MB instead.

Redefining the config will not let another (out-of-source) driver be

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

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
and SRAM regions, respectively. In this way we can cover the
entire Flash and SRAM space each with a single MPU region, thus,
save two MPU regions to be used by the kernel/application.

CPU_LPS_n name used to indicate a low power state is cryptic and
incorrect. The low power states act on the whole SoC and not exclusively
on the CPU. This patch renames CPU_LPS_n states to LOW_POWER_n. Also
HAS_ pattern for Kconfig options is used in favor of a non standard
_SUPPORTED. Naming of deep sleep states was adjusted accordingly.
Following is a detailed list of string replacements used:
s/SYS_POWER_STATE_CPU_LPS_(\d)_SUPPORTED/HAS_STATE_LOW_POWER_$1/
s/SYS_POWER_STATE_CPU_LPS_(\d)/SYS_POWER_STATE_LOW_POWER_$1/
