Kernel: Fix glitched audio output in SB16 driver

We were not setting the DMA transfer mode correctly. I have absolutely
no clue how this could ever have worked, but it did work for months
until it suddenly didn't.

Anyways, this fixes that. The sound is still a little bit glitchy and
that could probably be fixed by using the SB16's auto-initialized mode.
