Currently in some cases SDRAM init requires global_data to be available and soon this will not be available prior to board_init_f(). Adjust the code paths in these cases to be correct. In some cases we had the SPL stack be in DDR as we might have large stacks (due to Falcon Mode + Environment). In these cases switch to CONFIG_SPL_STACK_R. In other cases we had simply been setting CONFIG_SPL_STACK into SRAM. In these cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also in SRAM) so drop those lines.
