i386: Mark NUMA support experimental
I did some testing and found quite a lot of problems (doesn't
boot at all on non NUMA and misassigns cores on Opteron systems).
Mark it as experimental and warn against its use for now.
It's still default y for SUMMIT/NUMAQ because it'll presumably
work on these systems.
