Paul Mundt 896f0c0e8e sh: Support SCHED_MC for SH-X3 multi-cores.
This enables SCHED_MC support for SH-X3 multi-cores. Presently this is
just a simple wrapper around the possible map, but this allows for
tying in support for some of the more exotic NUMA clusters where we can
actually do something with the topology.
