3.8.13.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lorenzo Pieralisi <lorenzo.pieralisi at arm.com>

commit 1ba9bf0a9ae779c1a2b3eb64951e4161d9bad7a9 upstream.

The introduction of the cpu-map topology node in the cpus node implies
that cpus node might have children that are not cpu nodes. The DT
parsing code needs updating otherwise it would check for cpu nodes
properties in nodes that are not required to contain them, resulting
in warnings that have no bearing on bindings defined in the dts source file.
