[PATCH] ppc64: Set memory-only nodes online

From: Olof Johansson <olof@austin.ibm.com>

On pSeries LPARs we might end up with NUMA nodes that only have memory and
no CPUs.  Only the CPU configuration code actually set a node online, so
memory-only nodes wouldn't show up in sysfs.  Below patch adds the
set_online call to the memory loop too.
