PS12:
Do you have to do anything special to make a PS/2 mouse work?
Nope, it just works automatically in Devuan Daedalus (Linux 6.1 and Xfce 4.18).
Kinda makes sense, since in vendor firmware there's also no setting to choose between a mouse and a keyboard.
But on the other hand I recall seeing some other board in coreboot that had some issues with PS/2 mice connected like this.

The function will no-op itself if this config is not selected, so it's not necessary.
Ack. Having the "if" here makes more sense imo. But yeah it's a bit redundant at the moment. Many other boards do this too, perhaps we should consistently have one style or the other.
