drm/radeon: rework audio detect (v4)
1. Always assign audio function pointers even if the display does
not support audio. We need to properly disable the audio stream
when when using a non-audio capable monitor. Fixes purple line
on some hdmi monitors.
2. Check if a pin is in use by another encoder before disabling
it.
v2: make sure we've fetched the edid before checking audio and
look up the encoder before calling audio_detect since
connector->encoder may not be assigned yet. Separate
pin and afmt. They are allocated at different times and
have no dependency on eachother.
v3: fix connector fetching in encoder functions
v4: fix missed dig->pin check in dce6_afmt_write_latency_fields
