pc-dimm: get memory region from ->get_memory_region()
Curretly, the memory region of backed memory is all directly mapped to guest's address space, however, it will be not true for nvdimm device if we introduce nvdimm label which only can be indirectly accessed by ACPI DSM method Also it improves the comments a bit to reflect this fact Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.
