[Freedreno] [PATCH] drm/msm/dp: do not notify audio subsystem if sink doesn't support audio

[Abhinav Kumar]

For sinks that do not support audio, there is no need to notify
audio subsystem of the connection event.

This will make sure that audio routes only to the primary display
when connected to such sinks.
