PCI/cardbus: Add a fixup hook and fix powerpc
The cardbus code creates PCI devices without ever going through the necessary fixup bits and pieces that normal PCI devices go through. There's in fact a commented out call to pcibios_fixup_bus() in there, it's commented because ... it doesn't work. I could make pcibios_fixup_bus() do the right thing on powerpc easily but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus for which a weak empty implementation is provided by the PCI core. This fixes cardbus on powerbooks and probably all other PowerPC platforms which was broken completely for ever on some platforms and since 2.6.31 on others such as PowerBooks when we made the DMA ops mandatory (since those are setup by the fixups).
