Lars-Peter Clausen f02ba999ae axi_dmac: Add support for DMA bus widths other than 64 bit 
There were a few place in the core where it assumed a 64-bit wide bus. Make this
configurable using parameters. The patch also adds support for having different
DMA bus widths on the source and destination side.
