gw: get LiteEth working!
...
Link comes up! Not working fully, but that could be firmware too

gateware: fix dumb mistakes
...
Bus widths should now all be correct. (addresses and sizes in amaranth
take into account the granularity selection, so granularity acts like
two extra bits on the bus address line)
Also don't ignore a warning about undriven resets. Turns out that can
gate *everything* off in your design.

gateware: propogate MDIO signal correctly w/o IOBUF
...
This was causing my nextpnr crash. I really do need to figure out how to
do this in a less hacky way. Or even just make it more explicit that I
am doing this for a reason.

TODO is make a proper clock gen object, maybe it could run ecppll by
itself?

It's pretty hacky tbh, probably should be improved.
But also this will probably scale with the entire project so I don't
care.
