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?

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.

gateware: first work with I2C peripheral
...
Basic details seem to be working, and I'm on my way with testing.
Next steps:
- Build out more local testing utilities
- Build out unittest infrastructure
- Flesh out more tests to verify operation

- The Record.connect() function returns statements that need to be added

needs to be adjusted there
