commit 21635d7311734d2d1b177f8a95e2f9386174b76d upstream.
Commit 7769db588384 ("drm/i915/dp: optimize eDP 1.4+ link config fast and narrow") started to optize the eDP 1.4+ link config, both per spec and as preparation for display stream compression support.
Sadly, we again face panels that flat out fail with parameters they claim to support. Revert, and go back to the drawing board.
v2: Actually revert to max params instead of just wide-and-slow.
