PCI: Assign resources for hot-added host bridge more aggressively
When hot-adding an ACPI host bridge, use pci_assign_unassigned_root_bus_resources() instead of pci_assign_unassigned_bus_resources(). The former is more aggressive and will release and reassign existing resources if necessary. This is safe at hot-add time because no drivers are bound to devices below the new host bridge yet.
