ENGR00224245 HDMI AUDIO: stop/start PCM while unplug,blank/plug, unblank

When unplug, blank happens, HDMI audio can't play properly. So in
driver, audio pcm would be disconnected when event above happens.
However, pulse audio can't process disconnect event properly and if an
blank or unplug event happens, HDMI sink would lost and can't be back
again.

In this patch, instead of disconnecting audio PCM stream, triggering
stop audio pcm while unplug and blank, triggering start again while plug
and unblank if the audio pcm is triggerd stop in the unplug/blank event.
