There's a potentiometer connected to ADC1 and ADC2 in0 on
stm32h743i-eval board.
- Add fixed-voltage 'vdda' regulator that supplies 'vref' pin.
It's used as voltage reference for ADC and/or DAC.
- Enable ADC1 in0 input (arbitrary choice: could be ADC2 as well).
Note: No pinctrl is needed to use in0 dedicated analog input pin
(e.g. ADC12_INP0).
