The eDP spec claims a 20% overhead for the 8:10 encoding scheme used on the
wire. Take this into account when picking the lane/clock speed for the panel.

This also didn't fix the Dell E6410. I'll also note this in the bug.
I'm trying to work with some contacts at Dell to get this routed to
the right person as well...but am having limited luck with that, so
far.

So the previous fix didn't work for everyone, I read the eDP spec and claims a
20% overhead for encoding, so make sure we take this into account when working
out the bandwidth requirements.
This makes my eDP panel happy also, please test on others.

We've just gotten an eDP laptop, and kms was booting to a black screen.
as much as I hate Keith's magic * 3, it seems to work a lot better than the
non-magic.
aligning the non-magic seems to make things a lot happier, and aligns better
with what the bios appears to do, since
