[PATCH] sh: DMA updates
This extends the current SH DMA API somewhat to support a proper virtual
channel abstraction, and also works to represent this through the driver model
by giving each DMAC its own platform device.
There's also a few other minor changes to support a few new CPU subtypes, and
make TEI generation for the SH DMAC configurable.
