Looks like almost all changes to this driver had been tree-wide

The driver is using virt_to_bus() and is a real magnet for pointless
cleanups. It seems unlikely to have real users. Let's try to shed
this maintenance burden.

Removing this driver will kill support for some rather old PowerMac
models (some PowerBooks I think, paulus would know). No objection on my
part, though. I doubt people still use these things with new kernels
but ... who knows ? :-)
