[ALSA] hda-codec - optimize resume using caches

So far, the driver looked the table of snd_kcontrol_new used for creating
mixer elements and forces to call each of its put callbacks in PM resume
code.  This is too ugly and hackish.
Now, the resume is simplified using the codec amp and command register
caches.  The driver simply restores the values that have been written
in the cache table.  With this simplification, most codec support codes
don't require any special resume callback.
