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 at 15:power-domain at 16:power-domain at 18: 'power-domain at 19', 'power-domain at 20', 'power-domain at 21' do not match any of the regexes: 'pinctrl-[0-9]+'
