[U-Boot] [PATCH 1/2] mx51evk: support new relocation scheme

[Shawn Guo]

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.
