Better fix

Looks like I jumped the gun with the patch a bit. I thought we had a way to
detect eDP panels from the DPCD data, but it turns out we can't. So the
previous patch would mistakenly identify any DP display as eDP, which is
clearly not what we want.

I couldn't find any other way to detect eDP than to consul the VBT. Let's hope
it has the correct information.

Please re-test with this new patch.
