Just like pci_scan_bus(), we also should rip out
pci_bus_add_devices() from pci_scan_root_bus().
Lots platforms first call pci_scan_root_bus(), but
after that, they call pci_bus_size_bridges() and
pci_bus_assign_resources(). Place pci_bus_add_devices()
in pci_scan_root_bus() hurts PCI scan logic.
For arm hw_pci->scan() functions which call
pci_scan_root_bus(), it's no need to change anything,
because pci_bus_add_devices() will be called later
in pci_common_init_dev().

To: linux-arm-kernel
Now we could pass PCI domain combined with bus number
in u32 argu. Because in arm/arm64, PCI domain number
is assigned by pci_bus_assign_domain_nr(). So we leave
pci_scan_root_bus() and pci_create_root_bus() in arm/arm64
unchanged. A new function pci_host_assign_domain_nr()
will be introduced for arm/arm64 to assign domain number
in later patch.
