[PATCH] PCI: Export pci_cfg_space_size

The powerpc PCI code sets up the PCI tree without doing config space
accesses in most cases, from the firmware tree. However, it still wants
to call pci_cfg_space_size() under some conditions, thus it needs to
be made non-static (though I don't see a point to export it to modules).
