[PATCH v2 0/4] ALSA/ASoC: Conditionally skip i915 init and cleanups

[Cezary Rojewski <cezary.rojewski@xxxxxxxxx>]

A small set of changes to improve initialization of the audio stack on
HDAudio devices and pair of cleanups.

As the first change is the most important one here, following is the
technical background for it:

Commit 78f613ba1efb ("drm/i915: finish removal of CNL") and its friends
removed support for i915 for all CNL-based platforms. HDAudio library,
however, still treats such platforms as valid candidates for i915
binding. Update query mechanism to reflect changes made in drm tree.

At the same time, i915 support for LKF-based platforms has not been
provided so remove them from valid binding candidates.

The snd_soc_hda change is a follow up for the above and the cleanup
patches do not bring any functional changes.

Changes in v2:
- list of problematic VGA devices is now declared locally, no more
  touching drm stuff
