[PATCH] dt-bindings: mediatek: cec: Correct the compatibles for mt7623-mt8167

[Luca Leonardo Scorcia]

The HDMI CEC driver for both mt7623 and mt8167 is actually the same as
mt8173-cec and the mt7623n.dtsi board include file already uses mt8173-cec
compatible as a fallback, but the documentation lists them as separate
entries. Correct the binding by adding the correct fallback.

This change fixes a dtbs_check error.
