I think one thing should meantion is ARM-TF has another fixing:
https://github.com/96boards-hikey/arm-trusted-firmware/commit/543f1db7fd7e0aadcf947adedd63eaed817ef402

If you are using latest boot images, you should have included this
change int ARM-TF. This change is merged into ARM-TF at last year,
but just ensure this is not a block issue at your side.
