cr50: Store console lock state in NvMem vars.
This commit enables the use of the nvmem vars module. The console lock
state is migrated from using the long life scratch register, to nvmem
vars instead which will persist across power on reboots.
BUG=b:35586145
BRANCH=None
TEST=Flash a dev image. Lock the console. Remove all power from the
system. Power on system and verify that console is still locked.
Unlock the console, remove power from the system, power on the system,
verify that the console is now unlocked.
TEST=Repeat the above test, but using the nvtestvar console command
instead.
