drm/i915: Consolidate plane 'cleanup' operations (v3)
All plane update functions need to unpin the old framebuffer when
flipping to a new one. Pull this logic into a separate function to ease
the integration with atomic plane helpers.
v2: Don't wait for vblank if we don't have an old fb to cleanup (Ander)
v3: Really don't wait for vblank if we don't have an old fb to cleanup.
Previous version only handled this for primary planes; we need the
same change on cursors/sprites too! (Ander)
