This allows us to remove the dependency on device_type property for cpu nodes though removing that from DTS files will have to wait for some time. In some cases, this makes the DT search more strict by only looking in /cpus child nodes rather than any node with the device_type == cpu. The iterator also honors the status property which is often forgotten. I've only tested on ARM under QEMU and compiled powerpc.
