mm: drop CONFIG_HAVE_ARCH_NODEDATA_EXTENSION
There are no users of HAVE_ARCH_NODEDATA_EXTENSION left, so
arch_alloc_nodedata() and arch_refresh_nodedata() are not needed anymore.
Replace the call to arch_alloc_nodedata() in free_area_init() with a new
helper alloc_offline_node_data(), remove arch_refresh_nodedata() and
cleanup include/linux/memory_hotplug.h from the associated ifdefery.
