as SRAM

-A_007662 states that for x1 link width, PCIe2 controller trains in
Gen1 speed while configured for Gen2 speed.
Workaround:Set the width to x1 and speed to Gen2 by writing to
CCSR registers in PBI phase
-A_008007 states that PVR register may show random value.
Workaround: Reset PVR register using DCSR space in PBI phase
Add PBI based software workaround for A_007662 and A_008007
in t104x_pbi.cfg. This is required for SPL-based bootloaders
like NAND-boot, SD-boot, SPI-boot

Add support of 2 stage NAND, SD, SPI boot loader using SPL framework.
here, PBL initialise the internal SRAM and copy SPL(160KB). This further
initialise DDR using SPD and environment and copy u-boot(768 KB) from NAND to DDR.
Finally SPL transer control to u-boot.
Initialise/create followings required for SPL framework
- Add spl.c which defines board_init_f, board_init_r
- update tlb and ddr accordingly
