Add audio support for it6505
1. 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.

Hello Jiaxin,
this patch doesn't apply anymore (and it won't build anymore) upstream.

...and because you'll have to change this one, and other occurrences of that
as well.
