[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

This reverts commit 777226dac058d119286b4081953cb5aa2cb7394b.

Approach taken in the patch was rejected by Linus and the upstream tree
now already contains the required include directive via 304ac8032d3f
("Merge tag 'drm-next-2021-11-12' of git://anongit.freedesktop.org/drm/drm").
