ACPI: NFIT: Move bus_dsm_mask out of generic nvdimm_bus_descriptor
Browse files Browse the repository at this point in the history 
DSMs are strictly an ACPI mechanism, evict the bus_dsm_mask concept from
the generic 'struct nvdimm_bus_descriptor' object.

As a side effect the test facility ->bus_nfit_cmd_force_en is no longer
necessary. The test infrastructure can communicate that information
directly in ->bus_dsm_mask.
