[Intel-gfx] [PATCH 4/8] drm/i915: Pass in plane state when (un)pinning frame buffers

[Tvrtko Ursulin]

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

Plane state carries the rotation information which is needed for determining
the appropriate GGTT view type.

This just adds the parameter with the actual usage coming in future patches.
