The STM32MP13x platforms have a RNG hardware block that supports
customization, a conditional reset sequences that allows to
recover from certain situations and a configuration locking
mechanism.

This series adds support for the mentionned features. Note that
the hardware RNG can and should be managed in the secure world
for this platform, hence the rng not being default enabled on
the STM32MP135F-DK board.

Changes in V2:
	- Use pm_ptr() and add __maybe_unused on PM API
	- Correct bug using WARN_ON

Changes in V3:
	- Squash of bindings patches
	- st,rng-lock-conf property declaration rework
	- Fix stm32_rng_pm_ops declaration in patch [5/9]
