Anas Nashif a2fd7d70ec cleanup: include/: move misc/util.h to sys/util.h
move misc/util.h to sys/util.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Aurelien Jarno 5aa09c6baa drivers: entropy: stm32: add support for STM32F7
All the STM32F7 SoCs have a TRNG. Adding support for it is just a matter
of tweaking the #ifdef and including the right file from HAL.

Kumar Gala b92a40a798 drivers: entropy: stm32: Remove STM32F411XE from building
It appears the STM32F411XE doesn't support RNG so remove enabling it
from the SoC defconfig and flag an error if attempting to build the
driver on that SoC.

Erwan Gouriou 164fb32cf6 drivers: entropy: stm32: limit driver to SoC supporting it
In STM32 family, RNG IP is available only on F4 and L4 series.
Besides STM32F401 does not support is neither.
Get entropy driver available on STM32 devices supporting it and
generate a compilation issue on STM32 devices that do not own
the RNG IP.

Solves #5448

Erwan Gouriou 48ff51af75 drivers: entropy: Clock activation is missing on stm32l4
On STM32L4 SoCs RNG is clocked by 48MHz domain.
Hence, besides clock activation, it requires 48M
domain to be enabled.

Tested on:
*nucleo_l476rg
*stm32l476g_disco
*disco_l475_iot1

Leandro Pereira 8b883a61a3 subsys/random: sys_rand32_get() implementation that uses entropy API
Instead of every hardware number generator driver providing an
implementation of this function, use the random device API to
centralize the implementation of this function.

This is a very simplistic function that can be seen as a stepping stone
to refactor the random number generation in Zephyr.

Leandro Pereira da9b0ddf5b drivers: Rename `random` to `entropy`
This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware.  Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.
