In our OEM projects, we often meet this issues, there is no any monitor plugged,
but in the gnome-sound-setting, there are 4 hdmi/dp audio devices.

We check the eld_valid when reporting the hdmi/dp jack event

[Test Case]
On the problematic machines, we do s3 test without plugging monitor, there
is no hdmi audio device in the sound-setting.
On the machines without this problem, we do s3 test, pluggin/unplugging
monitor test, the hdmi audio work well as before.

[Regression Risk]
Low. We have done many tests on machines with or without this problem,
there is no regression so far.

  ALSA: hda/hdmi - Read the pin sense from register when repolling
  ALSA: hda/hdmi - Consider eld_valid when reporting jack event
