dt-bindings: display: mediatek: dp: Reference common DAI properties
The MediaTek DP hardware supports audio and exposes a DAI, so the
'#sound-dai-cells' property is needed for describing the DAI links.
Reference the dai-common.yaml schema to allow '#sound-dai-cells' to be
used, and filter out non-DP compatibles as MediaTek eDP in the same
binding doesn't support audio.
This fixes dtbs_check error:
'#sound-dai-cells' does not match any of the regexes: 'pinctrl-[0-9]+'
