[alsa-devel] A few more codecs for hda-emu

Hi Takashi,

I imported a few AD, IDT and VIA codec descriptions from codecgraph into the hda-emu codec collection. These bare bare codec info files instead of alsa-info output and can be replaced when better information becomes available. I can provide individual patches but you'll probably find it more convenient just to pull from git://github.com/cmatsuoka/hda-emu.git.
