Remove all init functions that do nothing, and provide a `NULL` to
*DEVICE*DEFINE* macros.

To deassert reset in STM32MP1 RCC the driver needs to set the bit in
reset clear register.
This patch extends existing implementation to support this type of
register.

This driver exposes STM32 RCC reset functionality through reset API.
Information about RCC register offset and bit is encoded just like GD32.
The first 5 least significant bits contains register bit number.
Next 12 bits are used to keep RCC register offset. Remaining bits are
unused.
