Introduce a generalized DAC binding that can be used by DACs that have
similar properties adding output-range-microamp and output-range-microvolt.

"for DAC channels"

Can't this be more simply written as

oneOf:
  - required:
      - output-range-microamp
  - required:
      - output-range-microvolt

required:
 - reg

 ?

I was following the structure used in adc.yaml.
Yes, I think we can simplify it with that.
