Treat SND_JACK_AVOUT as HDMI audio jack

Add detection logic for jacks that emit SND_JACK_AVOUT and treat that as
HDMI audio. Separate the logic from headphone, lineout and microphone to
avoid conflict and allow the use case for switching between HDMI audio
and headphones.

For Android desktop devices the HDMI audio jack is defined to emit
SND_JACK_AVOUT.
