xilinx_axi*: Re-implemented interconnect
Re-implemented the interconnect between the Xilinx AXI ethernet and DMA
controllers. A QOM interface "stream" is created, for the two stream interfaces.
As per Edgars request, this is designed to be more generic than AXI-stream,
so in the future we may see more clients of this interface beyond AXI stream.
This is based primarily on Paolos original refactoring of the interconnect.
