Added a DT schema for describing nau8325 audio amplifiers.

Please test your bindings before sending.

okay, thanks.

okay, I will use standard unit suffixes.

okay, I will use standard unit suffixes.

in Volts?

yes, this is Volts.

Volts/Volts

So 2 different units?

Both units are volts. I will modify the enum definition.
