MLK-22749 imx8mq: Add workaround to fix sticky bits lock up

On B1 chips with HAB v4.4, the sticky bits are not locked up in
HAB closed mode. We introduce a workaround in SPL to lock up
these bits and clear Manufacturing Protection Private Key for
secure boot.

For field return case, user has to build a SPL with
CONFIG_SECURE_STICKY_BITS_LOCKUP=n and set CONFIG_IMX_UNIQUE_ID to
part's unique id. When the UID check is passed, sticky bits are not
lockup and users can burn field return fuse. Otherwise the boot will
stop.
