Imx6 SPI flash change

Due to an EOL the SPI flash on this product is changing. In adding support for its replacement two drop in spi flashes were also added.

The old part is a Micron N25Q064A13ESE40F. Two new parts were qualified in in case this happens in the future, support will already be present for a spare. The new parts are the Microchip's SST26VF064BA, and ISSI's IS25LP064A.

Most applications will not be affected by this change unless they are manually accessing /dev/mtdblock, or creating a custom u-boot. In those cases some updates will be required.
