entropy_nrf5 modules uses k_sem_xxx() functions in several
places, but these functions are only functional when
CONFIG_MULTITHREADING is set, otherwise they just fallback to
the empty weak implementation provided in
zephyr/lib/libc/armstdc/src/threading_weak.c.

mcux_rnga driver calls k_cycle_get_32() which is not available
if CONFIG_SYS_CLOCK_EXISTS is not defined. Therefore we add
this depedendency to CONFIG_ENTROPY_MCUX_RNGA.

Automatically enable ENTROPY_GENERATOR if the device-tree has
any "zephyr,entropy" chosen property specified. This helps
in having CONFIG_ENTROPY_HAS_DRIVER set if the platform support
an entropy driver and this then enables CONFIG_CSPRNG_ENABLED.

On platforms like nrf5340 there are 2 CPUs:
- one is the cpu_net which takes care of the radio stuff and
owns the HW random generator
- one is the cpu_app which holds application data and polls
cpu_net through HCI commands when it needs some random data.
The PSA core implemented in Mbed TLS needs random data at initialization
time, which happens early in the boot process. If we wait for BT to
be ready before issuing the HCI command, then PSA core intialization
will fail. In facts there is no need for the BT to be completely
initialized just to ask for some random data from the cpu_app to
the cpu_net since the HW random generator will likely be already
functional in the cpu_net.
So let's just try the HCI command and, if something is not right,
it will fail anyway. There's no need to anticipate the failure.

Provide a new kconfig option which can be used to disable
the default seeding of the host standard library random
generator by this driver.
This allows some other component to do so without this component
default initialization interfering.

Removed PM device runtime support from drivers in PD_SYS domain.
Update the rest device drivers to call pm_device_runtime_get/put()
functions when CONFIG_PM_DEVICE_RUNTIME is enabled.

Add a semaphore to protect the disable access to the RNG peripheral
when the PM is going to suspend mode.
The change does not affect other stm32 than CONFIG_SOC_SERIES_STM32WBX
or CONFIG_STM32H7_DUAL_CORE

Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
Most of the changes here are scripted, check the PR for more
info.

This commit should optimize the way the device is allowed
to enter the suspended state. Instead of returning a PM
error code to abort the PM process, the standby power state
is constrained as long as the device is not allowed to enter
suspension. With that approach, acquiring PD_SYS is not needed
when in PM device runtime mode.

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.

It is done to make sure the interrupt is always enabled. The CR register
