da850evm: setup NAND support under CONFIG_USE_NAND

Browse source 
The current da850evm config is missing the pieces for NAND support that can be
found in Sandeep's u-boot-davinci tree [1].

This patch adds NAND support in the spirit of the support in the u-boot-davinci
tree where NAND support for the da850evm can be enabled by putting a single
'#define CONFIG_USE_NAND' at the top of the include/configs/da850evm.h file.
