Now that we have hooks to enable the atomic plane helpers, we can use the plane helpers for our .update_plane() and .disable_plane() entrypoints. Note that we still need to make a few small behavioral changes to the driver entrypoints here as we make the transition, due to differences between how the atomic helpers set things up for us vs how our internal functions were setting things up. v2: Fix commit message typo (Bob) v3: Rebased on top of Gustavo Padovan's patches to kill off intel_crtc_cursor_set_obj() and intel_pipe_set_base(). v4: Rebase again on latest display refactor series. Now that previous patches have smoothed the rough edges of the existing display code, the transition here is much less painful. v5: Plane helpers will re-prepare the same fb for a plane. Drop the WARN on this condition.
