As we are running into issues where the final U-Boot FIT image file is exceeding our size limit, add a hint to the README.sunxi64 file to point out the possibility of building non-debug versions of the ATF binary. These are about 12KB smaller than the standard debug build, and so allow successful U-Boot builds for many boards with the Allwinner H5 SoC. Please note that under normal circumstances the debug build is still recommended, as it gives valuable clues in case something goes wrong in the ATF.
