ALSA: hda - Add the generic Headphone Mic feature
This patch improves the generic parser code to allow to set up the headphone jack as a mic input. User can enable this feature by giving hp_mic hint string. The former shared hp/mic feature for the single built-in mic is still retained. This detection can be disabled now via hp_mic_detect hint string, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
