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.

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

Thanks.  Applied to the togreg branch of iio.git and pushed out as
testing for the autobuilders to play with it.
