ALSA: hda - Fix double-headphone/speaker paths for Cxt auto-parser
When multiple headphones or speakers are assigned but no individual DACs are available, the driver should take the first HP/SPK DAC instead of another primary output. The patch adds a bit-flag to dac field of struct pin_dac_pair indicating that it's a slave DAC. Signed-off-by: Takashi Iwai <tiwai@suse.de>
