Nouveau - Apr 2016 - [PATCH] secboot: print status message on success

Ourput an info message when secure boot has been successfully performed.
This is useful when troubleshooting issues that may be caused by
firmware loading being delayed - without an explicit message we have no
way to know whether secure boot has been performed or not.

This has been inspired by Ilia's comment on FD bug 94725. Will be useful
to have for future cases like this one.
