[RFT PATCH v2 10/42] PCI: Make pci_register_host_bridge() PCI core internal

[Lorenzo Pieralisi]

With the introduction of pci_scan_root_bus_bridge() there is no
need to export pci_register_host_bridge() to other kernel subsystems
other than the PCI compilation unit that needs it.

Make pci_register_host_bridge() static to its compilation unit and
convert the existing drivers usage over to pci_scan_root_bus_bridge().
