[PATCH v4 2/6] dt-bindings: phy: rockchip: naneng-combphy: Add power-domains property

Though isn't described in existing devicetrees, most Rockchip combphys
belong to a specific power-domain of the SoC. Taking RK3588 as example,
combphy 0 and combphy 2 belong to the PD_BUS domain. Document the
power-domains property to allow describing the information correctly
in devicetree.
