rockchip/rk3399: Move TTB to the end of SRAM

Browse source 
We found that we may want to load some components of BL31 on the RK3399
into SRAM. As usual, these components may not overlap any coreboot
regions still in use at that time, as is already statically checked by
the check-ramstage-overlaps rule in Makefile.inc.

On RK3399, the only such regions are TTB and STACK. This patch moves the
TTB region back to the end of SRAM (right before STACK), so that a large
contiguous region of SRAM before that remains usable for BL31.

BRANCH=gru
BUG=None
TEST=Booted Kevin.
