Cr50: Enable restricted console commands
This enables restricted console commands, meaning that only the
"help" command would be available when the Cr50 console is locked.
To get out of (or into) the locked state, this also adds a "lock"
command. Of course, it will be available in locked mode.
For now, the lock state is disabled, so all commands continue to
work as before. Even after enabling the lock, it's trivial to
disable it again. Future CLs will build on this framework.
