Add a command line option which will seed the random generator
from /dev/urandom.
This can be usefull for some particular tests in which we are
interested in having different random numbers in each run,
but we cannot provide a different random seed from command line.

With PM, when resuming from low power mode, reenable the RNG register
clocks and check the health register. If it is not set to the desired
value, it means we exit Suspend to RAM mode, and that the RNG needs to be
reinitialized.

STM32WBA controller uses a PKA driver to perform cyphering operations
on keys. Since PKA hardware block requires RNG clock to be enabled, a
synchronization with zephyr RNG driver is needed.
Use RNG enable status to check if RNG could be switched off or needs to
be switched on.
Similarly in entropy driver, don't cut RNG clock if PKA is enabled.

Quite a few of the drivers meant for the POSIX arch

Clang doesn't support push_options, pop_options and optimize pragmas.
Since "Ofast" is only applied to rng_pool_get() we can use function

Please note that clang doesn't support applying optimizations to

The CAAM hardware needs to read RNG values into a non-cache

RNG clock configuration constraints differ between each series.
Rather than providing complex build time code to verify RNG clock
configuration is correct, take advantage of CECS bit (Clock error
current status) to assess clock configuration.
This check is implemented under a specific ENTROPY_STM32_CLK_CHECK
Kconfig option. This allows user to disable this feature in specific
conditions:
- CED bit disabled in application (in which case CECS status is not valid)
- Clock configuration is deemed as correct by user. Note that RNG number
are always generated, whatever the clock status.
