This patchset enables nvdimm hotplug support, it is used as pc-dimm hotplug,
for example, a new nvdimm device can be plugged as follows:
object_add memory-backend-file,id=mem3,size=10G,mem-path=/home/eric/nvdimm3
device_add nvdimm,id=nvdimm3,memdev=mem3

and unplug it as follows:
device_del nvdimm3
object_del mem3
