Use SMPS power supply only if enabled.
The default power supply configuration for the
NUCLEO board with -Q subfix is SMPS,
so it's essential to match with hardware configuration
to avoid deadlocks due to mismatch.
if a custom board with LDO configuration is in use,
then no need to enable `CONFIG_POWER_SUPPLY_SMPS`

Refactors all of the clock control drivers to use a shared driver class
initialization priority configuration,
CONFIG_CLOCK_CONTROL_INIT_PRIORITY, to allow configuring clock control
drivers separately from other devices. This is similar to other driver
classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_OBJECTS or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
The even lower defaults for STM32 and Arm Beetle are preserved by
SoC-family level overrides.

When exiting Stop mode, if system clock is MSI, MSI oscillator is
selected as wakeup from stop clock; otherwise HSI16 oscillator is
selected.
It is otherwise reconfigured as MSI just after, but it slightly
increases the wake-up time and power consumption.

Following the migration of the clock source configuration in DTS (commit
2691541ad2), HSI is always used as wake-up source on STM32LX. It is
reconfigured as MSI just after, but it slightly increase the wake-up
time and power consumption.
It happens as the file defining STM32_SYSCLK_SRC_MSI is not included.
Fix that.

It happens that CM7 wakeups CM4, before CM4 goes to sleep.
Thus when CM4 goes to sleep,
there no more wakeup from CM7. And CM4 hangs.
For a simple synchronisation implementation,
CM4 doesn't go to sleep any more,
instead it waits (active wait) for CM7 to take HSEM
(meaning that clock configuration is finished).

CONFIG_PM_DEVICE was a de-facto requirement when enabling CONFIG_PM=y
since some device, i.e. UART, used the PM device hooks to block
suspension process while the device was busy finishing transmission.
This has now been fixed using constraints, so CONFIG_PM=y can be enabled
without further requirements.

Low power modes entry on stm32wb depends on requests coming from both
cores, with no consideration of the fact that C2 is booted or not.
By default, set C2 power mode to shutdown at C1 start up.
If required, it will be updated by C2.
In case C2 is not started, this will allow C1 to enter any power mode
with no dependency on C2.
