[PATCH] PCI Hotplug/powerpc: module build break

The RPAPHP hoplug driver will not build as a module, because it calls
on pci_claim_resource(), which is not exported. This exports the symbol.
Problem reported by Olaf Hering <olh@suse.de>

A grep indicates that building drivers/parisc/lba_pci.c
would have trouble building as a module for the same reason.
