Brian Norris 67b9bcd369 mtd: spi-nor: fix Spansion regressions (aliased with Winbond) ... Spansion and Winbond have occasionally used the same manufacturer ID, and they don't support the same features. Particularly, writing SR=0 seems to break read access for Spansion's s25fl064k. Unfortunately, we don't currently have a way to differentiate these Spansion and Winbond parts, so rather than regressing support for these Spansion flash, let's drop the new Winbond lock/unlock support for now. We can try to address Winbond support during the next release cycle.
