board/ti/am335x: update configs for parallel NAND
This patch - consolidate CONFIG_SYS_NAND_xx and CONFIG_SPL_NAND_xx from various configuration files into single file. - update MTD Partition table to match AM335x_EVM DT in linux-kernel - segregate CONFIGs based on different boot modes (like SPL and U-Boot) Signed-off-by: Pekon Gupta <pekon@ti.com>
