3b2af908c7 gw: get LiteEth working!
Link comes up! Not working fully, but that could be firmware too

8d00e15835 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.

8b19464608 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.

56d13a0e77 gateware: add PLL and generate two clocks
TODO is make a proper clock gen object, maybe it could run ecppll by
itself?

ad3be1f4c7 gateware: put in some testing infrastructure
It's pretty hacky tbh, probably should be improved.

But also this will probably scale with the entire project so I don't
care.
