nvdimm/cxl/pmem: Add support for master passphrase disable security command

Browse source

The original nvdimm_security_ops ->disable() only supports user passphrase
for security disable. The CXL spec introduced the disabling of master
passphrase. Add a ->disable_master() callback to support this new operation
and leaving the old ->disable() mechanism alone. A "disable_master" command
is added for the sysfs attribute in order to allow command to be issued
from userspace. ndctl will need enabling in order to utilize this new
operation.
