[HMM 01/16] mm/memory/hotplug: add memory type parameter to arch_add/remove_memory

When hotpluging memory we want more information on the type of memory. This is to extend ZONE_DEVICE to support new type of memory other than the persistent memory. Existing user of ZONE_DEVICE (persistent memory) will be left un-modified. Signed-off-by: Jérôme Glisse Cc:
