I can confirm it's in the tree.

Sure, I'll use this branch to test again.

Like my previous comment, the kernel was built against this commit:
commit c4fb60b9aba9f939d3f8575df23fd8d5958ec6ed
(drm-intel/drm-intel-next-queued)
Author: Jani Nikula <<a href="mailto:jani.nikula@intel.com">jani.nikula@intel.com</a>>
Date: Thu Jan 18 17:33:10 2018 +0200
drm/i915/bios: add DP max link rate to VBT child device struct
All three commits you mentioned are included.
The nightly part was to explain how kernel in [1] gets built. It's kinda
irrelevant in this context though.
