[ALSA] hda-codec - Don't build boost controls for digital mics
The ALC auto-probe creates mic boost controls automatically for the probed pins, but it assumes that they are analog mics. The digital mics have no boost controls and must be skipped. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
