The crossbar for eDMA works exactly the same way as sDMA, but sDMA
requires an offset of 1, while no offset is needed for eDMA.

The DRA7x has more peripherals with DMA requests than the sDMA can handle:
205 vs 127. All DMA requests are routed through the DMA crossbar, which can
be configured to route selected incoming DMA requests to specific sDMA
request.
