This is basically a merge of the previous port, the Zynq7000 port and
the port suggested by Pete Bone <[email protected]>.

This is how it is supposed to be used.
Also the set of the multi-cast hash enable bit was missing.

The same effect can be achieved but the code is simpler.

There are already a lot of differences between Zynq and
xilinx_ultrascale port, so there is no need to keep compatibility.

This map makes sure the correct interrupt id is registered in the
interrupt controller.
E.g. 'XPAR_XEMACPS_0_BASEADDR' is Canonical for the first interface
and can be mapped to any of the GEMs. 'XPAR_XEMACPS_0_INTR' on the
other hand is fixed to GEM0. This is why this mapping is needed.
