Document support for STM32MP1 ADC. It's quite similar to STM32H7 ADC.
Introduce "st,stm32mp1-adc" compatible to handle variants of this
hardware such as vregready flag, interrupts, clock rate.
Signed-off-by: Fabrice Gasnier <fabrice.gasnier@xxxxxx>

Changes in v2:
- Update dt-bindings following Rob's remark: STM32MP1 ADC has two
interrupt lines
