dt-bindings: display: mediatek,od: Add mediatek,gce-client-reg property
Currently, users of Mediatek OD (display overdrive) DT bindings set
mediatek,gce-client-reg node property, which is missing from the DT schema.
For example, device tree arch/arm64/boot/dts/mediatek/mt8173.dtsi is
causing the following dtb check error:
arch/arm64/boot/dts/mediatek/mt8173-elm.dtb: od@14023000 (mediatek,mt8173-disp-od): 'mediatek,gce-client-reg' does not match any of the regexes: '^pinctrl-[0-9]+$'
This commit adds the missing node property in the DT schema and updates the
example as well.
