mx51evk: support new relocation scheme
This patch is to fix build breakage and support new relocation
scheme for mx51evk.
- Correct IRAM base address and add size definition
The IRAM starts from 0x1FFE0000 on final revsion i.mx51 than
0x1FFE8000 which is for older revision.
- Include imx-regs.h in mx51evk.h
Definitions like CSD0_BASE_ADDR and IRAM_BASE_ADDR can be
referred to.
- Define CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE
They are used to define init RAM layout.
- Remove comment for CONFIG_SYS_GBL_DATA_SIZE which has been
buried by Wolfgang's commit below
25ddd1fb: Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
