The underlying issue breaking Spansion flash has been fixed with "mtd: spi-nor:
wait until lock/unlock operations are ready" and "mtd: spi-nor: wait for SR_WIP
to clear on initial unlock", so we can support unlocking for Winbond flash
again.
This is necessary to have writable flash on certain UBNT devices with some
bootloader versions.
