[PATCH v2 01/13] ASoC: dt-bindings: Convert MT8173 AFE binding to dt-schema

[Chen-Yu Tsai <wenst@chromium.org>]

Convert the MT8173 AFE (audio frontend) binding from text to dt-schema
in YAML. "clocks" is added to the list of required properties to match
"clock-names". And the example was slightly fixed up in style. Otherwise
everything is as before.

A contributer and maintainer for a recently added MediaTek audio binding
was chosen instead of the original submitter.
