[Intel-gfx] [PATCH] drm/i915: make edp optimize config

[matthew.s.atwood at intel.com]

From: Matt Atwood <matthew.s.atwood at intel.com>

Previously it was assumed that eDP panels would advertise the lowest link
rate required for their singular mode to function. With the introduction
of more advanced features there are advantages to a panel advertising a
higher rate then it needs for a its given mode. For panels that did, the
driver previously used a higher rate then necessary for that mode.
