drm/mediatek: Fix cursor plane no update 

The cursor plane should use the current plane state in atomic_async_update
because it would not be the new plane state in the global atomic state
since _swap_state happened when those hook are run.

Fix cursor plane issue by below modification:
1. Remove plane_helper_funcs->atomic_update(plane, state) in
   mtk_drm_crtc_async_update.
2. Add mtk_drm_update_new_state in to mtk_plane_atomic_async_update to
   update the cursor plane by current plane state hook and update
   others plane by the new_state.

Fixes: 37418bf14c ("drm: Use state helper instead of the plane state pointer")
