Revert "drm/i915: reverse dp link param selection, prefer fast over wide again"
This reverts commit 38aecea0ccbb909d635619cba22f1891e589b434.
This breaks Haswell Thinkpad + Lenovo dock in SST mode with a HDMI monitor attached.
Before this we can 1920x1200 mode, after this we only ever get 1024x768, and
a lot of deferring.
This didn't revert clean, but this should be fine.
