ALSA: hda - Expose secret DAC-AA connection of some VIA codecs
VT1718S and co have a secret connection from DAC to AA-mix, which doesn't appear in the connection list obtained from the h/w. Currently the driver fixes the connection index locally at init, but now we can expose it statically via snd_hda_override_connections() so that this conection can be checked better by the parser in future.
