Correct the binding by adding the correct fallback. Fixes the following dtbs_check error in mt7623n-rfb-emmc.dts and mt7623n-bananapi-bpi-r2.dts: i2c@11013000 (mediatek,mt7623-hdmi-ddc): compatible: ['mediatek,mt7623-hdmi-ddc', 'mediatek,mt8173-hdmi-ddc'] is too long Signed-off-by: Luca Leonardo Scorcia Reviewed-by: Krzysztof Kozlowski --- Changes in v2: Simplified error description in commit message.
