This series adds support for digital-to-analog converter on
stm32mp157c-ed1 board:
- define pins that can be used for DAC
- configure DAC channels to use these

Define pins that can be used by digital-to-analog converter on
stm32mp157c eval daughter board:
- PA4 and PA5 pins are available respectively on JP11 and JP10

stm32mp157c-ed1 board has digital-to-analog converter signals routed
to JP11 and JP10 jumpers (e.g. PA4/PA5).
It's easier then to configure them both. But keep them disabled by default,
so the pins are kept in their initial state to lower power consumption.
This way they can also be used as GPIO.
