This patch is to fix build breakage and support new relocatoin
scheme for mx51evk.
- It includes imx-regs.h in mx51evk.h, so that CSD0_BASE_ADDR and
IRAM_BASE_ADDR can be referred to.
- It uses i.mx51 internal RAM as the init stack, as the internal
RAM is totally free from ROM code when u-boot lives.
