I'd like to not introduce new support for SPI NOR controller drivers
(those under drivers/mtd/spi-nor/controllers/) so that we motivate the
owners to move their drivers to SPI. So we may have to rewrite the
helpers a bit, but I won't stumble on this right now, let me get the
general idea of read while write support first.
