Lars-Peter Clausen dc7b3e085c axi_dmac: Fix issues with non 64-bit AXI masters
Make sure that the address generator behaves correctly when the buswidth is not
64-bit. Also since the source and destination can have different widths add
separate parameters for source and destination address alignment.

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.

Lars-Peter Clausen 8326022adc axi_dmac: address_generator: Fix disable race condition
If the address generator is disabled the very same cycle as it tries to put a
new address on the bus, it will keep sending this address forever and the core
will lock up
