Bug description:
  On a Dell icelake platform, the hdmi audio doesn't work at all, when users
  plug hdmi cable, they can't find hdmi audio from gnome-sound-setting.

  add icl hdmi audio id and related support patch to alsa driver.

  [Test Case]
  after applying the patchset, we plug hdmi cable and the hdmi audio shows up
  in the sound-setting and works well, after unplugging the cable, the hdmi
  audio disappears as expected.

  [Regression Risk]
  Low. this patchset is specific to a icl hdmi audio codec.
