Add one optional property "rockchip,hdmi-codec" to let user specify HDMI device node in DTS so machine driver can find hdmi-codec device node for HDMI codec DAI. Use the presence of rockchip,audio-codec and rockchip,hdmi-codec to specify the use case. Use max98090 only : specify rockchip,audio-codec. Use HDMI only: specify rockchip,hdmi-codec. Use both max98090 and HDMI: specify rockchip,audio-codec and rockchip,hdmi-codec. Move these properties to optional because they are not needed for HDMI-only use case.
