Add support to artiq-zynq for EBAZ4205.

Testing:

  • MonInj (LEDs, GPIO)
  • Experiments (LEDs, GPIO)
  • Analyzer (LEDs, not GPIO)

Note: artiq_coreanalyzer -p shows the GPIO toggling but I have not been able to get it to view in the waveform viewer of the dashboard.

This should be a commandline option (e.g. --no-xtal), rather than uncommenting

Yes, agreed. This board is known to come in different variants on the 2nd hand market and I don't feel like removing the xtal to test things as my board has the xtal populated. I will remove this commented out code and leave the commandline option for a possible future branch.

Fair enough, don't add anything that's not been tested either.

Might be simpler to either (1) add a dummy module with I2C functions that always return error/false, or (2) dedicate two I/O pins on the board to I2C since many use cases will want it anyway.

I am open to either option. Note that if I did go with (2), dedicating two I/O pins, I would need to update zynq-rs for this as well. What do you deem the better option?

Another zynq-rs update is not a problem, but if it's too contrived, you may go with dummies for now and add I2C support later.

125MHz would be a more sensible default.

And I think most other programs use - not _ in command line arguments.
