[PATCH 04/54] ASoC: dt-bindings: Convert Simple Amplifier binding to a schema

Simple audio amplifiers are supported by Linux with a matching device
tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

-Optional properties:
-- enable-gpios : the gpio connected to the enable pin of the simple amplifier
