Subject[PATCH 1/15] x86, sched: Add config option for multi-node CPU scheduling

I've decided to add this as a subitem of MC scheduling.
I think the normal case will be that a multi-node CPU has more than 1
core on each of its nodes. Thus using MN scheduling without MC
scheduling does not make much sense.
