nvdimm acpi: initialize the resource used by NVDIMM ACPI
32 bits IO port starting from 0x0a18 in guest is reserved for NVDIMM
ACPI emulation. The table, NVDIMM_DSM_MEM_FILE, will be patched into
NVDIMM ACPI binary code
OSPM uses this port to tell QEMU the final address of the DSM memory
and notify QEMU to emulate the DSM method
