MLK-14375-1 mx6ullevk: Update board codes to align with v2016.03
Update mx6ull evk to add features from v2016.03.
1. Add support for NAND flash.
2. Add support for QSPI DM driver.
3. Add USB DM driver support.
4. Add two FEC support by using DM FEC driver
5. Update environments for various boot devices support: SD/NAND/eMMC/QSPI
6. Add MFGtool environments.
7. Add board codes for 9x9 EVK board
For the DTS file, some changes are needed for using QSPI DM driver
1. Add spi0 alias for qspi node. Which is used for bus number 0.
2. Modify the n25q256a@0 compatible property to "spi-flash".
3. Modify spi4 (gpio_spi) node to spi5
