Subject: [PATCH] dt-bindings: display: mediatek: dp: Add #sound-dai-cells property

The MediaTek DP hardware supports audio, and the "#sound-dai-cells"
property is required to describe DAI links and audio routing.

Add "#sound-dai-cells" property to the binding and filter out non-DP
compatibles, as MediaTek eDP doesn't support audio.
