ALSA: hda - Check NO_PRESENCE pincfg default bit
HD-audio spec defines a bit in pin default configuration for indicating that the pin isn't used for jack-detection although the codec is capable of it. Better to check this bit as well in jack_is_detectable() helper function. Reported-by: Raymond Yau <superquad.vortex2@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
