dt-bindings: iio: stm32-adc: add support for STM32MP1 



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.

- interrupts: One or more interrupts for ADC block. Some parts like stm32f4

  and stm32h7 share a common ADC interrupt line. stm32mp1 has two separate

  interrupt lines, one for each ADC within ADC block.

- clocks: Core can use up to two clocks, depending on part used:

  - "adc" clock: for the analog circuitry, common to all ADCs.
