PCI: Delay final fixups until resources are assigned
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
[bhelgaas: changelog, move fixups to pci_bus_add_device()]
