drm/i915: Move rotation from intel_plane to drm_plane_state
Runtime state that can be manipulated via properties should now go in
intel_plane_state/drm_plane_state so that it can be tracked as part of
an atomic transaction.
We add a new 'intel_create_plane_state' function so that the proper
initial value for this property (and future properties) doesn't have to
be repeated at each plane initialization site.
v2:
- Stick rotation in common drm_plane_state rather than
intel_plane_state. (Daniel)
- Add intel_create_plane_state() to consolidate the places where we
have to set initial state values. (Ander)
