i915: fix ironlake edp panel setup (v4)
The eDP spec claims a 20% overhead for the 8:10 encoding scheme used on the wire. Take this into account when picking the lane/clock speed for the panel. v3: some panels are out of spec, try our best to deal with them, don't refuse modes on eDP panels, and try the largest allowed settings if all else fails on eDP. v4: fix stupid typo, forgot to git add before amending.
