A quick look at the Linux driver suggests that they treat AMDIF031 as the
other amdgpio devices, but with 24 pins, not 8 [1, 2]. That doesn't quite
map onto our amdgpio driver though (where `npins` is 184 pins)? But I
suppose if my machine doesn't use it, there's no way I can test it!

A bit more time with the machine has shown that it has more problems than I
first realised. In particular, things randomly stop working (notably iwx and
input into X, where it won't respond to keyboard/mouse, but I can
Ctrl+Alt+F1 switch to the console and work fine there), and only a hard
reboot fixes them. I'm not quite sure what to make of that: there's no
obvious trigger, and the machine can last anywhere from about 14-45 minutes
before hitting such an issue.
