acpi, nfit: Add function to look up nvdimm device and provide SMBIOS handle
EDAC driver needs to look up attributes of NVDIMMs provided in SMBIOS.
Provide a function that looks up an acpi_nfit_memory_map from a device
handle (node/socket/mc/channel/dimm) and returns the SMBIOS handle.
Also pass back the "flags" so we can see if the NVDIMM is OK.
