The Cr50 console provides access to all sorts of dangerous
commands. To protect user secrets, we must erase the persistent
storage before unlocking the console.
Note that this will not powerwash the AP, leaving you with the
impression that you've just forgotten your password. You'll have
to manually powerwash (Ctrl+Alt+Shift+R) afterwards. That will be
addressed in a future CL.

BRANCH=none
TEST=make buildall, test on Gru
Lock the console if it's not already ("lock enable"), then unlock
it with "lock disable". Confirm that the NVMEM region is erased
following a successful unlock process.
