The problem of using auto ID is that the device name will be like hdmi-audio-codec.<id number>.auto.
The number might be changed when there are other platform devices being created before hdmi-audio-codec device. Use a fixed name so machine driver can set codec name on the DAI link.
Using the fixed name should be fine because there will only be one hdmi-audio-codec device.
Fix the codec name in rockchip rk3288_hdmi_analog machine driver.
