PCI: Move cpci_hotplug_init() proto to header file
cpci_hotplug_init() and cpci_hotplug_exit() are defined in cpci_hotplug_core.c but had extern declarations in pci_hotplug_core.c. This puts the declarations in a header file included both places so the compiler can help keep everything consistent. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
