common/flash: Add option to set PSTATE to be locked by default
For hammer, we do not want to require finalization in factory, so
we just protect RO whenever WP GPIO is set.
BRANCH=none
BUG=b:63378217
TEST=Enable CONFIG_FLASH_PSTATE_LOCKED, flash hammer,
check with flashinfo that RO protection matches WP status.
