The MT8167 SoC have a hard limit on the maximal supported HDMI TMDS clock, and is not validated and supported for HDMI modes out of HDMI CEA modes.
To achieve this: - switch the mediatek HDMI bindings to YAML - add the MT8167 compatible - add a boolean to discard the non-CEA modes - add a value to specify mac TMDS supported clock - add a conf entry for the MT8167 compatible
