powerpc/pseries: Auto-online hotplugged memory
A recent update (commit id 31bc3858ea3) allows for automatically
onlining memory that is added. This patch sets the config option
CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE=y for pseries and updates the
pseries memory hotplug code so that DLPAR added memory can be
automatically onlined instead of explicitly onlining the memory.
