Not sure if VDMA support would be worth it...
IMO, it is useless. It requires per-IRQ handling of each DRQ block,
which just adds complexity to existing "PIO-ish" data paths. You have
to set up and tear down DMA engine for each DRQ block.
VDMA would be far more useful if it handled the entire transfer in one
go, like a normal BMDMA transaction.
