These two functions allow drivers to reuse their atomic plane helpers functions for the primary plane to implement the interfaces required by the crtc helpers for the legacy ->set_config callback. This is purely transitional and won't be used once the driver is fully converted. But it allows partial conversions to the atomic plane helpers which are functional. v2: - Use ->atomic_duplicate_state if available. - Don't forget to run crtc_funcs->atomic_check. v3: Shift source coordinates correctly for 16.16 fixed point. v4: Don't forget to call ->atomic_destroy_state if available. v5: Fixup kerneldoc. v6: Reuse the plane_commit function from the transitional plane helpers to avoid too much duplication. v7: - Remove some stale comment. - Correctly handle the lack of plane->state object, necessary for transitional use. v8: Fixup an embarrassing h/vdisplay mixup.
