Kenji Kaneshige 151ab36a2e PCI: fix wrong assumption in pci_find_upstream_pcie_bridge ...

Current pci_find_upstream_pcie_bridge() has a wrong assumption that
pci_bus->self is NULL on the root pci bus. But it might not true on
some platforms. Because of this wrong assumption, current
pci_find_upstream_pcie_bridge() might cause endless loop. We must
check pci_bus->parent instead.
