Initialize audio_comp when audio starts and wait for audio_comp at
dp_display_disable(). This will take care of both dongle unplugged
and display off (suspend) cases.
Changes in v2:
-- add dp_display_signal_audio_start()
Changes in v3:
-- restore dp_display_handle_plugged_change() at dp_hpd_unplug_handle().
Changes in v4:
-- none
