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

As far as I see, all those 4 patches are rather individually applicable, right? The essential change is the first patch, and the patch 2 is rather an improvement (the driver gives -ENODEV as of now). And the rest two are merely cleanups.
