dmaengine: omap-dma: move register read/writes into omap-dma.c
[ Upstream commit 596c471b69249764d8e241b004736878204daa0f ]
Export the DMA register information from the SoC specific data, such
that we can access the registers directly in omap-dma.c, mapping the
register region ourselves as well.
Rather than calculating the DMA channel register in its entirety for
each access, we pre-calculate an offset base address for the allocated
DMA channel and then just use the appropriate register offset.
