ALSA: hda - Create output controls according to pin types for IDT/STAC
Improve the parser to pick up more intuitive control names for the outputs judging from the pin type, instead of fixed names assigned to channels. Also, revive the multi-HP workaround since this change fixes the problem with the multi-HP detection. Signed-off-by: Takashi Iwai <tiwai@suse.de>
