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.

- compatible: Should be one of:
"st,stm32f4-adc-core"
"st,stm32h7-adc-core"
"st,stm32mp1-adc-core"
- reg: Offset and length of the ADC block register set.
- interrupts: Must contain the interrupt for ADC block.
- 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.
It's required on stm32f4.

stm32f4, that has per instance clock input for registers access.
