ASoC: hdac_hdmi: Add hotplug notification and read ELD

Browse source

This patch uses i915 component framework to register for hotplug
notification.

In the hotplug notification, driver reads pin sense and ELD by
sending PIN_SENSE and ELD verbs over HDA bus. Once it identifies
valid pin sense and valid ELD, store the ELD into the
corresponding pin map buffer.

Also read the monitor present sense during resume and ignore the
ELD notify from graphics during PM as is done in legacy hda,
commit 8ae743e82f ("ALSA: hda - Skip ELD notification during
system suspend")
