Oh, ok... I thought you did.

Right, normally we don't need any special handling since the DT has the
right names ... this machine just needs an override for the GPIO names
(gpio15/16 rather than the proper detect names).

Yeah, not really ... I wrote aoa, so I guess I'm biased, but really
snd-powermac is quite a mess.
