If you want to use a shared firmware target, then the pins should be kept as similar as possible between variants. Supporting different pin assignments based on board_id is not something we support in general. nivviks/nirwen was a special case.

We can always switch to board_id if really needed in the future, but I think this is fine for now, and we should try to make sure future hardware changes can be supported by fw_config too.
