PCB Feature Request: Plug-and-Play compatibility of ULX5M FPGA pinout to Olimex #12

In order to facilitate porting of apps and example across these two GateMate hardware platforms, ULX5M should strive to match Olimex pinout at FPGA level. With that, the GateMate gateware becomes platform-agnostics, which helps portability and ease of adoption. Even minor pinout discrepancies can cause major trouble, see https://github.com/chili-chips-ba/openCologne/issues/11#issuecomment-2156149819.

The ULX5M connector pinout naturally needs to conform to the CM4 spec. The gist of the challenge is therefore to map CM4-Connector to Olimex-FPGA pinout on the ULX5M SOM.
