imx: mx7dsabresd: support nand
Add pinmux settings. Add related macro definitions. Nand pin conflicts with emmc, so if want to enable nand, need to do hardware rework. After hardware rework, define CONFIG_NAND_MXS in board header file. Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Stefano Babic <sbabic@denx.de>
