PCI: convert pci_scan_bus() to use pci_create_root_bus()
I plan to deprecate pci_scan_bus_parented(), so use pci_create_root_bus() directly instead. pci_scan_bus() itself will be removed as soon as all callers are gone, so this is just an interim step. v2: export pci_scan_bus Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
