ti: armv7: Move SPL SDRAM init to the right place, drop unused CONFIG_SPL_STACK

Browse Source 
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.
