I'm not sure I agree.  It seems that specifying nodes for each DMA channel 
(virtual or physical) is meaningless because the only property in the node 
is the "reg", which is really just a cell-index in disguise.

My vote is to have a node only for the DMA engine, and let the DMA handle 
the virtual and physical channels internally.
