mtd: spi-nor: Add support for statefull Octal IO mode xSPI compliant flashes support only 1 bit mode or 8 bit DDR mode. Entering 8 bit DDR mode would require configuring certain registers in flash in 1 bit mode. This procedure varies across flash vendor. Also, different vendors require different number of wait cycles (dummy bytes) in Octal DDR mode. Therefore provide two callbacks for flashes: change_op() and adjust_op(). change_op() can be used for switching to Octal mode and adjust_op() to adjust protocol specific settings for OSPI.
