sound fixes for 4.4

A slightly higher volume than a new year's wish, but not too
worrisome: a large LOC is only for HD-audio device-specific quirks,
so fairly safe to apply.  The rest ASoC fixes are all trivial and
small; a simple replacement of mutex call with nested lock version,
a few Arizona and Realtek codec fixes, and a regression fix for
Skylake firmware handling.

ASoC: Last minute fixes for v4.4

A few final fixes for v4.4, the main one being the two patches to the
new Sky Lake drivers which fix a previous incorrect fix that went in
during an earlier -rc.
