[OpenBIOS] [PATCH] Expose PCI controller information

[Alexander Graf]

Linux tries to detect which PCI controller it's supposed to work with.
On PPC32 there is fallback code that doesn't get compiled with
CONFIG_PPC64, so we really have to expose a controller or we don't have
pci config space accessor functions.

Let's expose a un3-agp if we have a mac99 model, as that's what is
supposed to be in there anyways.
