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.thomp...@ge.com> "Davinci: NAND enable ECC even when not in
NAND boot mode"
