ASoC: dt-bindings: Add support for the GPIOs driven amplifier

Browse source

Some amplifiers based on analog switches and op-amps can be present in
the audio path and can be driven by GPIOs in order to control their gain
value, their mute and/or bypass functions.

Those components needs to be viewed as audio components in order to be
fully integrated in the audio path.

gpio-audio-amp allows to consider these GPIO driven amplifiers as
auxiliary audio devices.
