PATCH v2 1/1 ARM: configs: Add da850evm_nand to boot from NAND

The DA850-EVM supports booting from NAND when used with the UI expander board. da850evm_nand will create an ais file that can be burned to NAND and booted while storing the env in NAND along with some partitions tables for storing kernel, dtb and rootfs in NAND.
