The way of switching is through SOC_DAPM_PIN_SWITCH, however, such events can not be handled in hdmi-codec driver. So add event handler for hdmi TX to solve the above issue.

Bridge to hdmi-codec to support audio feature. At the same time, the function of automatically detecting audio is removed. 2. It is observed that some DP-to-HDMI dongles will get into bad states if sending InfoFrame without audio data. Defer to enable it6505's audio feature when PCM triggers START or RESUME.
