This reverts commit 0d71068835e2610576d369d6d4cbf90e0f802a71. Not only that the commit introduces a bogus check (voltage_tries == 5 will never meet at the inserted code path), it may bring the driver into an endless DP-link-train loop (and actually it does on HP Z1 with eDP).
We can add a better check for the intended purpose of that commit, but let's revert the wrong "fix" at first.
