ALSA: hda - drop def association and sequence from pinconf comparing
A lot a machine have the same codec, but they have different default pinconf setting just because the def association and sequence is different, as a result they can't share a hda_pintbl[], to overcome it, we don't compare def association and sequence in the pinconf matching.
