acpi/nfit, libnvdimm: Add support for issue secure erase DSM to Intel nvdimm
Add support to issue a secure erase DSM to the Intel nvdimm. The
required passphrase is acquired from an encrypted key in the kernel user
keyring. To trigger the action, "erase <keyid>" is written to the
"security" sysfs attribute.
