lgtm. Please push as soon as we've figured out what to do with patch 3.

I wonder whether we shouldn't change our DP code a bit and force the
port into normal mode (with some conservative link training values) even
when link training fails. Contrary to fdi links I think the pixels would
still flow and so would allow us to exercise more codepaths. But that's
for another time I guess.

Depending upon how the kms_ tests shape up we might want to extract a bit
more code from here, but again we can do that later.

Thanks, Daniel
