cxl/pmem: Add "Passphrase Secure Erase" security command support
Create callback function to support the nvdimm_security_ops() ->erase()
callback. Translate the operation to send "Passphrase Secure Erase"
security command for CXL memory device.
When the mem device is secure erased, cpu_cache_invalidate_memregion() is
called in order to invalidate all CPU caches before attempting to access
the mem device again.
See CXL 3.0 spec section 8.2.9.8.6.6 for reference.
