nfit: update address range scrub commands to the acpi 6.1 format
The original format of these commands from the "NVDIMM DSM Interface Example" [1] are superseded by the ACPI 6.1 definition of the "NVDIMM Root Device _DSMs" [2]. [1]: http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf [2]: http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf "9.20.7 NVDIMM Root Device _DSMs" Changes include: 1/ New 'restart' fields in ars_status, unfortunately these are implemented in the middle of the existing definition so this change is not backwards compatible. The expectation is that shipping platforms will only ever support the ACPI 6.1 definition. 2/ New status values for ars_start ('busy') and ars_status ('overflow').
