arm: ls102xa: Add NAND boot support for LS1021AQDS board
This patch adds NAND boot support for LS1021AQDS board. SPL framework is used. PBL initialize the internal RAM and copy SPL to it, then SPL initialize DDR using SPD and copy u-boot from NAND flash to DDR, finally SPL transfer control to u-boot.
