nextpnr/fpga-interchange: Fix 200t device

[ajelinski]

The device can't be built due to the OSError: [Errno 12] Cannot allocate memory error: https://github.com/hdl/conda-eda/runs/2504914939?check_suite_focus=true#step:3:4206

It seems to require more than the GH Action's 7GBs of RAM: https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources

For now the package will be built without this device.
