PCI: Delay final fixups until resources are assigned

commit e253aaf0af51c1e4dc7dd3b26ea8e666bf9a2d8d upstream.

Commit 4f535093cf "PCI: Put pci_dev in device tree as early as possible"
moved final fixups from pci_bus_add_device() to pci_device_add().  But
pci_device_add() happens before resource assignment, so BARs may not be
valid yet.

Typical flow for hot-add:

    pciehp_configure_device
      pci_scan_slot
        pci_scan_single_device
          pci_device_add
            pci_fixup_device(pci_fixup_final, dev)  # previous location
      # resource assignment happens here
      pci_bus_add_devices
        pci_bus_add_device
          pci_fixup_device(pci_fixup_final, dev)    # new location
