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

Browse Source 
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 the following dtbs_check errors:

DTC [C] arch/arm/boot/dts/mediatek/mt7623n-rfb-emmc.dtb
cec@10012000 (mediatek,mt7623-cec): compatible: ['mediatek,mt7623-cec',
  'mediatek,mt8173-cec'] is too long
DTC [C] arch/arm/boot/dts/mediatek/mt7623n-bananapi-bpi-r2.dtb
cec@10012000 (mediatek,mt7623-cec): compatible: ['mediatek,mt7623-cec',
  'mediatek,mt8173-cec'] is too long
