Revert "sunxi: Move the SPL stack top to 0x1A000 on Allwinner A64/A80"
This commit moved the SPL stack into SRAM C, which worked when the SPL
set the AHB1 clock down to 100 MHz to cope with the flaky SRAM C access
from the CPU.
However booting with boot0 (and thus not using SPL at all) we still run
with a 200 MHz AHB1, so any access to SRAM C is prone to fail.
Since this commit does _not_ only affect the SPL code, but also the
U-Boot proper, we fail when booting with boot0.
As the introduction of tiny-printf reduced the size of the SPL, we
can afford to have the SPL stack in SRAM A1.
This reverts commit 1a83fb4a17d959d7b037999ab7ed7e62429abe34
and fixes booting the Pine64 when using boot0.
