mtd: spi-nor: atmel: fix unlock_all() for AT25FS010/040
These flashes have some weird BP bits mapping which aren't supported in
the current locking code. Just add a simple unlock op to unprotect the
entire flash array which is needed for legacy behavior.
Fixes: 3e0930f109e7 ("mtd: spi-nor: Rework the disabling of block write protection")
