[Qemu-devel] [PATCH v2 3/3] pc-dimm: revert "introduce realize callback"

[Wei Yang <richardw.yang@linux.intel.com>]

realize callback in introduced to check if the backend memory is large
enough to contain label data and init its memory region, while this task
is handled in pre_plug stage.

Now it's time to remove it.
