It may be useful if the actual NVM authentication can be delayed to be
run later, for instance when the user logs out. For this reason add a
new NVM operation (AUHENTICATE_ONLY) that just triggers the authentication
procedure over whatever was written to the NVM storage.

This is not supported with Thunderbolt 1-3 devices, though.
