rng: stm32: Implement custom RNG configuration support

STM32 RNG configuration should best fit the requirements of the
platform. Therefore, put a platform-specific RNG configuration
field in the platform data. Default RNG configuration for STM32MP13
is the NIST certified configuration [1].

While there, fix and the RNG init sequence to support all RNG
versions.
