ALSA: hda - Disable static quirks for C-Media codecs

According to alsa-info.sh outputs, all three entries with static
quirks have the correct pin configs, so it's safe to remove static
quirks.  For now, turn the static quirks off via ifdef.  The dead
codes will be removed in later release.

ALSA: hda - Make snd_hda_gen_spec_free() static

The last user of snd_hda_gen_spec_free() is patch_via.c, and we can
rewrite it safely with snd_hda_gen_free(), so that
snd_hda_gen_spec_free() can be a local function in hda_generic.c.
