On IBM pseries systems the device_type device-tree property of a PCIe bridge contains the string "pciex". The of_bus_pci_match() function was looking only for "pci" on this property, so in such cases the bus matching code was falling back to the default bus, causing problems on functions that should be using "assigned-addresses" for region address translation. This patch fixes the problem by also looking for "pciex" on the PCI bus match function.
