The udl driver is the only caller of drm_plane_helper_atomic_check().
Move the function into the driver. No functional changes.

- * drm_plane_helper_atomic_check() - Helper to check plane atomic-state
- * @plane: plane to check

- * Provides a default plane-state check handler for planes whose atomic-state
- * scale and positioning are not expected to change since the plane is always
- * a fullscreen scanout buffer.
- *
- * This is often the case for the primary plane of simple framebuffers. See
- * also drm_crtc_helper_atomic_check() for the respective CRTC-state check
- * helper function.
- *
- * RETURNS:
- * Zero on success, or an errno code otherwise.
