ARM: configs: Add da850evm_nand to boot from NAND

Browse Source 
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.
