Enable additional HD-Audio codec information to be parsed using alsa-info script to generate codec information with CONFIG_SND_SOC enabled

Function group nodes -Add power state controls -Add subordinate node count parameters -Add function group type information -Add function group capabilities -Add unsolicited response controls -Add input converter SDI select information -Add GPIO enable control -Add GPIO direction information -Add GPIO wake enable information -Add GPIO unsolicited control information -Add GPIO sticky mask data -Add GPIO data sets associated with GPIO signals

Widget nodes -Add pin widget controls -Add power state controls -Add converter stream and channel controls -Add processing state information -Add processing capabilities -Add volume knob capabilities -Add volume knob control information -Add digital converter control information -Add pin sense control information -Add EAPD/BTL enable controls -Add unsolicited response controls
