ARM SysTick timer is implemented by default in ARMv7-M
and Mainline ARMv8-M processors, so we include the
corresponding Kconfig symbol in arch/arm/core/cortex-M/Kconfig
and remove the selections from the Cortex-M SOCs.

Add SYS_POWER_ prefix to HAS_STATE_SLEEP_, HAS_STATE_DEEP_SLEEP_
options to align them with names of power states they control.
Following is a detailed list of string replacements used:
s/HAS_STATE_SLEEP_(\d)/HAS_SYS_POWER_STATE_SLEEP_$1/
s/HAS_STATE_DEEP_SLEEP_(\d)/HAS_SYS_POWER_STATE_DEEP_SLEEP_$1/

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.

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/
s/SYS_POWER_STATE_DEEP_SLEEP_(\d)_SUPPORTED/HAS_STATE_DEEP_SLEEP_$1/

This commit removes dependency on SYS_POWER_LOW_POWER_STATES_SUPPORTED,
SYS_POWER_DEEP_SLEEP_STATES_SUPPORTED Kconfig options. Power management
SYS_POWER_LOW_POWER_STATES, SYS_POWER_DEEP_SLEEP_STATES options depend
now directly on specific power states supported by the given SoC. This
simplifies maintenance of SoC Kconfig files.

This commit adds sys_set_power_state() function with support for EM1
Sleep, EM2 Deep Sleep, EM3 Stop power modes on Silabs SoCs.
Tested on efr32_slwstk6061a board.
Note: No support for efm32hg, efm32wg series at this point due to the
missing possibility of placing function code in RAM, required by errata
in SiLabs library code.

This commit removes "select SYS_POWER_*_SUPPORTED" entries from
Kconfig on SoCs which are not implementing sys_set_power_state()
method used to control power mode.

The SYS_POWER_LOW_POWER_STATE_SUPPORTED and SYS_POWER_LOW_POWER_STATE
suggests one low power state but these options control multiple
low power state. This commit uses plural in the names to indicate
that.

Use the new DT_<COMPAT>_<INSTANCE>_<PROP> defines to instantiate
devices. This commit adds also ability to define individual pin
locations on SoC series that support the feature. Definitions of GPIO
pins assigned to a given location have been moved from soc_pinmap.h file
to board DTS file.

Zephyr gecko drivers depend on libraries provided by the vendor. The
same libraries may also be used directly by the application code or
RAIL library. To facilitate the latter use case scenario this commit
adds Kconfig options to independently enable compilation of vendor
HAL library modules.

This commit simplifies Kconfig options related to handling SoC series,
part numbers. This is a first step required to add remaining part
numbers to the existing configuration.
This change is possible since all SiLabs SoCs within a single series
have a very uniform structure.
