Yeah, that's my thinking. We should probably include eDP hooked up to
the PCH DP lanes (fo

We've always use

High frequency link configurations have the potential to cause trouble
with long and/or cheap cables, so prefer slow and wide configurations
instead. This patch has the potential to cause trouble for eDP
configurations that lie about available lanes, so if we run into that we
can make it condition
