PCI: convert pci_scan_bus_parented() to use pci_create_root_bus() 

This converts pci_scan_bus_parented() to use pci_create_root_bus()
instead of pci_create_bus().  The new bus still has the default (incorrect)
resources, so this patch doesn't help fix that problem, but it does remove
one more use of pci_create_bus().
