PCI: pciehp: cleanup flow in pciehp_configure_device
Move bus_size_bridges and assign resources out of pciehp_add_bridge()
and do them all together, one time, including slot bridge, to avoid to
calling assign resources several times when there are several bridges
under the slot bridge. Using pci_assign_unassigned_bridge_resources.
