[PATCH 6/9] powerpc/PCI hotplug: merge rpaphp_enable_pci_slot()

[John Rose]

Remove general baroqueness.  The function rpaphp_enable_pci_slot()
has a fairly simple logic structure, once all of the debug printk's
are removed. Its called from only one place, and that place also
has a very simple structure once he printk's are removed.  Merge
the two together.
