misc: stm32: Add STM32MP1 support
Following next kernel rcc bindings, we must use a MFD
RCC driver which is able to bind both clock and reset
drivers.
We can reuse and adapt RCC MFD driver already available
for MCU SoCs (F4/F7/H7).

Enable the STM32 RCC driver. The RCC block (Reset and Clock Control
block) is responsible of the management of the clock and reset
