ASoC: rockchip_max98090: Optionally support HDMI use case
Support three different use cases with rockchip_max98090 driver. The three use cases: - max98090 only: Current usage, where HDMI link is missing. - HDMI only: Needed use case for veyron_mickey board. - max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc. The presence of max98090 is determined by the presence of rockchip,audio-codec device property. The presence of HDMI is determined by the presence of rockchip,hdmi-codec device property. Create different sound card based on the configuration. Note that we keep max98090 only usage for backward compatibility.
