numa: ia64: support numa_mem_id() for memoryless nodes

Enable 'HAVE_MEMORYLESS_NODES' by default when NUMA configured on ia64.
Initialize percpu 'numa_mem' variable when starting secondary cpus.
Generic initialization will handle the boot cpu.

Nothing uses 'numa_mem_id()' yet.  Subsequent patch with modify slab to
use this.
