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.
Signed-off-by: Cheng-Yi Chiang cychiang@chromium.org --- The checkpatch reported error "Macros with complex values should be enclosed in parentheses". It is ignored because it does not suit the usage in this patch.
