[ALSA] hda - Avoid unexpected breakage with ALC889A hack
The last ALC889A hack may break on some devices with certain model presets since patch_alc*() have different model tables. So, now it's handled in the original patch_alc882() but fly to patch_alc883() in model=auto appropriately. Signed-off-by: Takashi Iwai <tiwai@suse.de>
