libnvdimm: Add DSM support for Address Range Scrub commands
Add support for the three ARS DSM commands: - Query ARS Capabilities - Queries the firmware to check if a given range supports scrub, and if so, which type (persistent vs. volatile) - Start ARS - Starts a scrub for a given range/type - Query ARS Status - Checks status of a previously started scrub, and provides the error logs if any. The commands are described by the example DSM spec at: http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf Also add these commands to the nfit_test test framework, and return canned data.
