[Intel-gfx] [CI 2/7] drm/i915: Move display related definitions to dedicated header
Chris Wilson

Thu Dec 21 21:57:30 UTC 2017
From: Michal Wajdeczko <michal.wajdeczko at intel.com>
We already have separate files for display related code, there
is no reason to keep all display definitions in master header.
