Add test which checks if a PCI device described in DT with an entry and reg = <...> property, but without compatible string results in a valid U-Boot PCI udevice with the udevice.node populated with reference to this DT node. Also check if the other PCI device without a DT node does not contain any bogus udevice.node.
