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

Message

A small set of changes to improve initialization of the audio stack on
HDAudio devices and pair of cleanups. While I did touch i915_pciids.h
header which is part of drm, I'd like the changes to go through Mark's
tree entirely - being cohesive with the rest of the code by adding LKF
IDs where they belong rather than hiding them within the sound tree.

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.
