[PATCH] alsa: ac97_patch make functions static

[Harvey Harrison <harvey.harrison@gmail.com>]

Only used in ac97_codec by including ac97_patch.c directly, effectively static

Found by sparse:
sound/pci/ac97/ac97_patch.c:3551:5: warning: symbol 'patch_vt1617a' was not declared. Should it be static?
sound/pci/ac97/ac97_patch.c:3767:5: warning: symbol 'patch_vt1618' was not declared. Should it be static?
