[PATCH v6 03/20] dt-bindings: power: mediatek: Refine multiple level power domain nodes

[Tinghan Shen <tinghan.shen@mediatek.com>]

Extract duplicated properties and support more levels of power
domain nodes.

This change fix following error when do dtbs_check,
    arch/arm64/boot/dts/mediatek/mt8195-evb.dtb: power-controller: power-domain@15:power-domain@16:power-domain@18: 'power-domain@19', 'power-domain@20', 'power-domain@21' do not match any of the regexes: 'pinctrl-[0-9]+'
