sh: Fix Dreamcast DMA issues.
The current SH DMA API is somewhat broken, not correctly matching
virtual channel to the correct SH DMAC. This wasn't noticeable when
using g2 DMA for the sound driver - one channel 0 is as good as any
other! - but caused the pvr2 driver to fail.
This patch fixes the pvr2 problem and consequently fixes the sound
driver to ensure it continues to function.
