Rob Herring 3d5089c426 of/address: Add support for 3 address cell bus
There's a few custom bus bindings (e.g. fsl,qoriq-mc) which use a
3 cell format with custom flags in the high cell. We can match these
buses as a fallback if we didn't match on PCI bus which is the only
standard bus binding with 3 address cells.
