Subject: [PATCH 00/21] DT cpu node iterator

This series adds an iterator for cpu nodes and converts users over to use
it or of_get_cpu_node in some cases. 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.
