Randall Spangler a47bda8042 Make flash_ec capable of writing to an incorrectly-protected STM32

If EC-RO protects itself via the WRPx option bytes, flash_ec will fail
to reprogram it.  And if EC-RO is broken/unbootable, it won't be able
to clear the WRPx option bytes itself when it sees the write protect
GPIO is not asserted.

Add the -u flag to stm32mon so that it will automatically attempt to
unprotect the flash via the option bytes.

BUG=chrome-os-partner:19723
BRANCH=none
TEST=enable write protect GPIO.  Then from console, 'flashwp enable'.
     Then from the chroot:
        ./util/flash_ec --board=pit --ro --image=build/pit/ec.RO.flat
     That should successfully reflash the board.
