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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
