PATCH 1/1 am33xx/omap4+: Move SRAM_SCRATCH_SPACE_ADDR to <asm/arch/omap.h>

The location of valid scratch space is dependent on SoC, so move that there. On OMAP4+ we continue to use SRAM_SCRATCH_SPACE_ADDR. On am33xx/ti814x we want to use what the ROM defines as "public stack" which is the area after our defined download image space. Correct the comment about and location of CONFIG_SPL_TEXT_BASE.
