cxl/pmem: Add Disable Passphrase security command support
Create callback function to support the nvdimm_security_ops ->disable()
callback. Translate the operation to send "Disable Passphrase" security
command for CXL memory device. The operation supports disabling a
passphrase for the CXL persistent memory device. In the original
implementation of nvdimm_security_ops, this operation only supports
disabling of the user passphrase. This is due to the NFIT version of
disable passphrase only supported disabling of user passphrase. The CXL
spec allows disabling of the master passphrase as well which
nvidmm_security_ops does not support yet. In this commit, the callback
function will only support user passphrase.
See CXL rev3.0 spec section 8.2.9.8.6.3 for reference.
