rand32.h does not make much sense, since the random subsystem
provides more APIs than just getting a random 32 bits value.
Rename it to random.h and get consistently with other
subsystems.

cleaned up some code in 3 mcux entropy drivers,
removing unnecessary void casts and function declarations

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Introduce Kconfig for setting the driver initialization priority across

Convert entropy drivers to use new DT variants of the DEVICE APIs.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Move towards use DTS for driver instance name instead of Kconfig sybmol.
This is towards phasing out CONFIG_ENTROPY_NAME.

move entropy.h to drivers/entropy.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.

To ensure that early code that requires entropy has the HWRNG devices
fully initialized, initialize them all during PRE_KERNEL_1 stage.

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.
Signed-off-by: Leandro Pereira <leandro.pereira@intel.com>
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.

Some "random" drivers are not drivers at all: they just implement the
function `sys_rand32_get()`. Move those to a random subsystem in
preparation for a reorganization.
