acpi/nfit: Add support for Intel DSM 1.8 commands
Add command definition for security commands defined in Intel DSM specification v1.8 [1]. This includes "get security state", "set passphrase", "unlock unit", "freeze lock", "secure erase", "overwrite", "overwrite query", "master passphrase enable/disable", and "master erase", . Since this adds several Intel definitions, move the relevant bits to their own header. These commands mutate physical data, but that manipulation is not cache coherent. The requirement to flush and invalidate caches makes these commands unsuitable to be called from userspace, so extra logic is added to detect and block these commands from being submitted via the ioctl command submission path. Lastly, the commands may contain sensitive key material that should not be dumped in a standard debug session. Update the nvdimm-command payload-dump facility to move security command payloads behind a default-off compile time switch.
