[PATCH] Enable audio at MSI Digivox AD II card

[PATCH] Enable audio at MSI Digivox AD II card

[Mauro Carvalho Chehab]

This device also uses audio on a separate USB interface. The new audio
handling works fine, but the GPIO settings, and I2C/XCLK speed need
some fixes.

Thanks to Oravecz to diagnose and get the right configs for the registers.

I'm waiting for Oravecz confirmation that this patch works like the changes he
originally made, but I'm forwarding the patch to the ML, in order to keep it
tracked via patchwork, and to allow others to test it.
