reset: stm32: Add support of MCU HOLD BOOT
Handle the register RCC_MP_GCR without SET/CLR registers
but with a direct access to bit BOOT_MCU:
- deassert => set the bit: The MCU will not be in HOLD_BOOT
- assert => clear the bit: The MCU will be set in HOLD_BOOT
With this patch the RCC driver handles the MCU_HOLD_BOOT_R value
added in binding stm32mp1-resets.h
