[PATCH 2/2] reset: stm32: drop STM32 MCU support in favor of simple reset driver

[Ahmad Fatoum]

RCC reset will eventually get more involved when we add SCMI support.
Linux already has reset and clock control in the same driver.

As we now have a simple driver that can toggle resets on the STM32 MCUs
as well, we can drop the now duplicate support from the dedicated
STM32 reset driver.
