CONFIG_SYS_INIT_SP_OFFSET macro place stack to TEXT_BASE - SYS_MALLOC_F_LEN but there is no reason to do it now because board_init_f_alloc_reserve() returns exact location where stack should be. That's why stack location is calculated at run time and there is no need to hardcode it via macro. This change will help with placing U-Boot to any address.
