On STM32MP13 SoCs, each ADC peripheral has a single ADC block.
These ADC peripherals, ADC1 and ADC2, are fully independent.
The STM32MP131 SoC provides only ADC2, while other STM32MP13x
SoCs provide both ADC1 and ADC2.

The STM32MP13 ADC features and characteristics are slightly
different from STM32MP15 ADC ones, requiring a specific support
in the driver.

This patchset enables the ADC peripheral on STM32MP135F-DK board.

On STM32MP135F-DK board the ADC is connected to VDDA voltage
provided by the PMIC LOD1 supply, which has to be enabled through
SCMI regulator framework.
This serie introduces a fixed regulator to allow ADC probing,
while SCMI regulators support is not available. This does
not ensure ADC regulator enabling however.

Changes in v4:
- reformat patch 1 commit message
- reorder adc1 node

v3:
- Remove blank line in tag block
- Use HZ_PER_MHZ unit for max frequency definition
- Coding style updates

v2:
- Rework commit message length
- Add missing spaces
- Remove useless defines
