[PATCH v5 3/5] drm: dw-hdmi-i2s: Use fixed id for codec device

[Cheng-Yi Chiang]

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.
