stm32_rng: driver for STM32 RNG

Drivers is embedded upon CFG_STM32_RNG=y.

The driver main API functions are:
- stm32_rng_read() to get a buffer of random bytes,
- stm32_rng_read_raw() to get a buffer of random bytes assuming the
RNG hardware is ready, i.e clock enabled.

The device driver is initialized from DT resource when a secure DTB,
currently the embedded DTB, is found.

STM32 RNG driver assumes the platform supports at most RNG instance
in the secure world.
