misc: fuse: Lock 8ULP ECC-protected fuse when programming

The ECC fuse on 8ULP can't be written twice. If any user did it, the
ECC value would be wrong then cause accessing problem to the fuse.
The patch will lock the ECC fuse word to avoid this problem.
For iMX9, the OTP controller automatically prevents an ECC fuse word to
be written twice. So it does not need the setting.
