sunxi: Enable CONFIG_SPL_STACK_R
Select CONFIG_SPL_STACK_R for sunxi boards, this gives us much more
room on the stack once we've the DRAM running.
Besides being a good change to have on itself, this also paves the
way for switching to using malloc_simple in the SPL which cuts of
close to 4KiB of the SPL size.
