[PATCH v3 3/6] dt-bindings: allow optional phys in Rockchip dw_hdmi binding

[Heiko Stuebner]

Some newer Rockchip SoCs use an Innosilicon hdmiphy accessed via general
mmio, so allow these to be referenced via the regular phy interfaces
and therefore add optional phy-related properties to the binding.
