[Intel-gfx] [RFC 3/3] drm/i915: Use intel_plane_obj_offset from more places

[Tvrtko Ursulin]

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

These are the display call sites so should use the proper helper.

Also requires intel_plane_obj_offset to assume normal view when
plane pointer is not available.
