Subject: [PATCH 5.1 80/85] drm: Expose "FB_DAMAGE_CLIPS" property to atomic aware user-space only

From: Deepak Rawat <drawat@...are.com>

commit c8f005684c98f4d9942baec13ad98054dbf312a0 upstream.

Plane property "FB_DAMAGE_CLIPS" can only be used by atomic aware
user-space, so no point exposing it otherwise.
