[PATCH v1 4/7] write WPEN bit for SST26* devices when locking

"sf protect lock" did only protect against accidental writes by software. it did not lock down the config or block-protection registers if the WP# pin was deasserted. hardware write protection was never enabled for these devices. this change implements setting the WPEN bit and clearing the IOC bit
