Function random_byte_get() returns only the least significant byte of
the 32-bit random datum, as this is the used value, so avoiding that
higher numbers are interpreted as negative error codes and their value
is not discarded.

Convert from device_get_binding to DEVICE_DT_GET. In doing this we
no longer need the label in the devicetree node so we remove that.
Removed all __ASSERT_NO_MSG(clk) since we'll get a build error if
DEVICE_DT_GET cant be satisfied, and the clock control api's will
handle reporting if the device_is_ready.

- Remove SYS_ prefix
- shorten POWER_MANAGEMENT to just PM

and use PM_ as the prefix for all PM related Kconfigs
Signed-off-by: Anas Nashif <anas.nashif@intel.com>
For drivers that support CONFIG_DEVICE_POWER_MANAGEMENT there are some
cases that look like:
#ifdef CONFIG_DEVICE_POWER_MANAGEMENT
DEVICE_DEFINE()
#else
DEVICE_AND_API_INIT()
#endif
There is no need to special case this as the pm_control_fn argument to
DEVICE_DEFINE will just be ignored in the
!CONFIG_DEVICE_POWER_MANAGEMENT case. So we can cleanup the code a
little and remove the #else cases for the drivers that do this.

RCC_HSI48_SUPPORT is not always defined even if SOC support HSI48.
Ex: STM32H7 family which support HSI48 but doesn't have
switch RCC_HSI48_SUPPORT.
This switch is usefull when in the same STM32 family some soc have
HSI487 and some other soc not.
So instead, use CMSIS register defines (which depends on family)

A non-blocking, isr-safe version of get_entropy() is necessary in order

Add the necessary clock configuration to support STM32L-based
SoCs. This change likely adds support for other STM32 SoCs as well
since the HSI48 clock is configured for all SoCs that support it
(except the STM32L4x) instead of just the STM32G4X.

The driver-specific config_info structure referenced from the device
structure is marked const. Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.
Changes produced by scripts/coccinelle/const_config_info.cocci.
Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.

Convert stm32 entropy driver to configuration based on device tree.
Select HAS_DTS_ENTROPY symbols and configure CONFIG_ENTROPY_NAME
in fixup files.
Since rng node is not enabled (or available) on all boards, it could
happen that symbol ENTROPY_STM32_RNG is not enabled and hence
ENTROPY_HAS_DRIVER not selected which ends up with a symbol
ENTROPY_NAME defined throufg Kconfig selection. Thus, in fixup file,
CONFIG_ENTROPY_NAME is defined only if not already defined.
Additionally, update boards that used to configure entropy by default.
On these boards, enable rng device in device tree and remove Kconfig
related configuration (which should not be part of default
configuration).
