It has been found out that in some HW combination the DisplayPort fast link training feature caused screen flickering. Let's revert this feature for now until we can ensure that the feature works for all platforms. This is a manual revert of commits 5fa836a9 ("drm/i915: DP link training optimization") and 4e96c977 ("drm/i915: eDP link training optimization"). Fixes: 5fa836a9 ("drm/i915: DP link training optimization") Fixes: 4e96c977 ("drm/i915: eDP link training optimization") Cc: <stable@vger.kernel.org> # v4.2+ Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91393Reviewed-by:
