devkit8000: Move CONFIG_SYS_TEXT_BASE out of bss

This moves CONFIG_SYS_TEXT_BASE one MB after beginning of SD-RAM. Move
CONFIG_SYS_SPL_MALLOC_START to have one MB of free space for the u-boot
image.

CONFIG_SYS_TEXT_BASE was in the middle of the bss-section. This was the
reason for the problems with MMC boot described here:
