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:

$ make CHECK_DTBS=y mediatek/mt8173-elm.dtb
   SCHEMA  Documentation/devicetree/bindings/processed-schema.json
   DTC [C] arch/arm64/boot/dts/mediatek/mt8173-elm.dtb
[...]
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.

I fixed up the commit msg with Krzysztof's comments and applied both 
display patches. Thanks!
