board/t208xqds: Add support of 2-stage NAND/SPI/SD boot

Browse Source 
Add support of 2-stage NAND/SPI/SD boot loader using SPL framework.
PBL initializes the internal CPC-SRAM and copy SPL(160K) to it,
SPL further initializes DDR using SPD and environment and copy
u-boot(768 KB) from SPI/SD/NAND to DDR, finally SPL transfers
control to u-boot.
