stm32mp: cmd_stm32key: lock of PKH OTP after fuse
Lock the OTP value of key's hash after the command
$> stm32key fuse <address>
This operation forbids a second update of these OTP as they are
ECC protected in BSEC: any update of these OTP with a different value
causes a BSEC disturb error and the closed chip will be bricked.
