[ALSA] Fix invalid 'AutoSync Reference' value

RME HDSP driver
The value returned by controllers for control number 14 ('AutoSync
Reference') is incorrect and different from that reported by doing
a cat /proc/asound/card0/hdsp.
The value reported is not 'AutoSync Reference' but 'Preferred Sync
Reference' instead.
