powerpc has implemented numa binding using property named
"ibm,associativity", we too started adding using the same binding[
refer version V6]
however had discussion/review with Mark R about mapping and we could not map to
some of the topology like mesh and ring topology.

So we have defined and implemented this new binding which is simple
and scalable.
This binding is very much aligned to ACPI NUMA specification.
