    drm/i915: reverse dp link param selection, prefer fast over wide again

    ... it's this time of the year again. Originally we've frobbed this to
    fix up some regressions, but maybe our DP code improved sufficiently
    now that we can dare to do again what the spec recommends.

    This reverts

        drm/i915: prefer wide & slow to fast & narrow in DP configs

    I'm pretty sure I'll regret this patch, but otoh I expect we won't
    make progress here without poking the devil occasionally.
