Integrate LiteETH

Create LiteEth rust driver

MVP is an implementation that works with smoltcp. Should be pretty easy.

I can bring up the ethernet link, so HW is validated, this isn't super high priority.

Add debug access to Minerva core

Unfortunately, it relies on jtagtap, which is written for nmigen.

To do this, I'll need to port it to amaranth. Shouldn't be a huge amount of work,…

Evaluate and create wishbone interface for amlib I2C device.

Evaluate and create wishbone interface for amlib I2C device.

There's still a couple open questions I have about I2CInitiator/I2CTarget interactions, but I have simulated a full R/W transaction on I2C, so I'm considering this good enough for now, I think any…
