[PATCH] powerpc: migrate common PCI hotplug code

23-rpaphp-migrate.patch (parts)

This patch moves some pci device add & remove code from the PCI
hotplug directory to the arch/powerpc/kernel directory, and cleans
it up a tad. The primary reason for this is that the code performs
some fairly generic operations that are shared with the PCI error
recovery code (living in the arch/powerpc/kernel directory).
