Enable ROCKCHIP_SPL_BACK_TO_BROM for rock2 board
Rock2 has been tested with back to brom feature. The tricky part is that with this feature the default environment is inside u-boot, and it's defined for every rk3288 board independetly. So I just changed it for rock2 here if ROCKCHIP_SPL_BACK_TO_BROM. Solve by moving environment after u-boot before 1M boundary Signed-off-by: Sandy Patterson <apatterson@sightlogix.com> Acked-by: Simon Glass <sjg@chromium.org>
