32 bits IO port starting from 0x0a18 in guest is reserved for NVDIMM

OSPM uses this port to tell QEMU the final address of the DSM memory
and notify QEMU to emulate the DSM method
Would you need to pass control to QEMU if each NVDIMM had its whole
label area MemoryRegion mapped right after its storage MemoryRegion?
No, label data is not mapped into guest's address space and it only
can be accessed by DSM method indirectly.
