arch, ia64: Make NUMA select SMP
While it does make sense to allow CONFIG_NUMA and !CONFIG_SMP in theory, it doesn't make much sense in practice. Follow other architectures and make CONFIG_NUMA select CONFIG_SMP. The motivation for this patch is to allow a new NUMA variable to be initialised in kernel/sched/topology.c.
