There is currently no NAND pinmux enabled by the da850evm board setup code. This is fine when booting from NAND since the early boot code (UBL) will setup the pinmux; however, when the boot mode is any other setting NAND is unusable when enabled in the config.
This patch adds a pinmux list for NAND and enables it when NAND is enabled in the config. Tested by booting from SPI on the da850evm and verifying NAND was usable.

Note: there is precendent for NAND configuration by u-boot independent of the selected boot mode; see commit 26be2c53d671ecfd3e0483f0870649ac28322293 by Nick Thompson nick.thompson@ge.com "Davinci: NAND enable ECC even when not in NAND boot mode"
