Benjamin Herrenschmidt 3e8ba96866 arm64: PCI: Allow resource reallocation if necessary 
Call pci_assign_unassigned_root_bus_resources() instead of the simpler:

  pci_bus_size_bridges(bus);
  pci_bus_assign_resources(bus);

pci_assign_unassigned_root_bus_resources() calls:

  __pci_bus_size_bridges(bus, add_list);
  __pci_bus_assign_resources(bus, add_list, &fail_head);

so this should be equivalent as long as we're able to assign everything.
If we were unable to assign something, previously we did nothing and left
it unassigned, but after this patch, we will attempt to do some
reallocation.

Once we start honoring FW resource allocations, this will bring up the
"reallocation" feature which can help making room for SR-IOV when
necessary.
