<pre>The original BYT dmesg is filled with display port link training issues. It's
obvious the resume time goes ballistic if we keep retrying the link training.
Also note that we get the panel power sequencing timings from VBT, so the panel
enable time even with the same panel is going to be different between HSW and
BYT.
I've fixed a number of DP link training issues lately. Please try the latest
drm-intel-nightly on BYT, and see if that helps. Attach dmesg with debugs
enabled if it still fails. Thanks.</pre>
