I don't have the same monitor but I don't have any problem lighting up with
HDMI 2.0 4k 60Hz with Alex's amd-staging-4.7 and the commit from a week ago:

commit 4fa58023f62a95e93f82a25cdceb87b19b69b27f
Author: Christian König <christian.koenig at amd.com>
Date:   Mon Oct 17 15:34:07 2016 +0200

    reservation: revert "wait only with non-zero timeout specified (v3)"

    This reverts commit fb8b7d2b9d80e1e71f379e57355936bd2b024be9.

    Otherwise signaling might never be activated on the fences. This can
    result in infinite waiting with hardware which has unreliable interrupts.

If you still see this issue please attach xorg log, dmesg and xrandr output, as
Alex suggested.
