[PATCH 06/22] dt-bindings: iio: dac: ad5686: rework on power supplies

[Rodrigo Alencar via B4 Relay]

From: Rodrigo Alencar <rodrigo.alencar@xxxxxxxxxx>

Add supplies for VDD, VLOGIC and VREF input voltage pins. The vcc-supply
property is deprecated. Certain devices require vref-supply to be
available once an internal reference voltage is absent. Still, this patch
does not add those as 'required' so that the ABI is not broken.
