Vivado 2014.4 is too greedy, when it needs to optimize. See more about the issue here: https://ez.analog.com/thread/48214
The response_dest_resp is unused, so not save to concatenate with a valid signal like the eot.
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.

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.
