TI:armv7: Change CONFIG_SPL_STACK to not be CONFIG_SYS_INIT_SP_ADDR
There are times where we may need more than a few kilobytes of stack
space. We also will not be using CONFIG_SPL_STACK location prior to DDR
being initialized (CONFIG_SYS_INIT_SP_ADDR is still used there) so pick
a good location within DDR for this to be. Tested on
OMAP4/AM335x/OMAP5/DRA7xx.
