powerpc/85xx: Use DDR for RAMBOOT instead of L2 SRAM on p1_p2_rdb
Using DDR as RAMBOOT base instead of L2SRAM for SDCard and SPI Flash
boot loaders because:
- P1_P2_RDB boards have soldered DDR so no need for SPD
- Also P102x has 256K L2 cache size so becomes a limiting factor for
size of image that could be loaded in SRAM mode and would require three
stage boot loader (TPL).
Changes done:
1. CONFIG_SYS_TEXT_BASE to 0x11000000
2. CONFIG_RESET_VECTOR_ADDRESS to 0x1107fffc
