Bug description:
  [Impact]
  HDMI audio is missing on Intel RKL.

  [Fix]
  Also use BIOS provided value for HDA link.

  [Test]
  HDMI audio is back after the fix gets applied.

  [Where problems could occur]
  Because this is a regression, this patch simply brings back the old
  behavior for RKL systems. There could be RKL systems get fixed by
  the offending commit, so this might break those hypothetical systems.
