Create callback function to support the nvdimm_security_ops() ->unlock()
callback. Translate the operation to send "Unlock" security command for CXL
mem device.
When the mem device is unlocked, cpu_cache_invalidate_memregion() is called
in order to invalidate all CPU caches before attempting to access the mem
device.
See CXL rev3.0 spec section 8.2.9.8.6.4 for reference.
