drm/imx: imx-ldb: Accept drm_of_find_panel_or_bridge failure
Not having an endpoint bound in DT should not cause a failure here, there are fallbacks. So explicitly accept a missing endpoint. This behavior change was introduced by refactoring in drm_of parsing code and it should not require dts changes. In particular this fixes imx6qdl-sabreauto boards.
