cxl/pmem: Introduce nvdimm_security_ops with ->get_flags() operation
Add nvdimm_security_ops support for CXL memory device with the introduction
of the ->get_flags() callback function. This is part of the "Persistent
Memory Data-at-rest Security" command set for CXL memory device support.
The ->get_flags() function provides the security state of the persistent
memory device defined by the CXL 3.0 spec section 8.2.9.8.6.1.
