Add struct nd_passthru_pkg which serves as a warapper for
the data being passed via a pass thru to a NVDIMM DSM.
This wrapper specifies the extra information in a uniform
manner allowing the kenrel to call a DSM without knowing
specifics of the DSM.
Add dsm_call command to nvdimm_bus_cmd_name and nvdimm_cmd_name.
