PCI: designware: Use pci_scan_root_bus() for simplicity
After b97ea289cf6a ("PCI: Assign resources before drivers claim devices (pci_scan_root_bus())"), pci_scan_root_bus() no longer adds the devices, so it is equivalent to: pci_create_root_bus() pci_scan_child_bus() Use pci_scan_root_bus() to simplify the code.
