If CONFIG_OF is disabled but we build any driver that tries to use of_get_display_timing, we get this link error: ERROR: "of_get_display_timing" [drivers/gpu/drm/rcar-du/rcar-du-drm.ko] undefined! This adds an empty inline function as an alternative, to avoid changing each driver using this function when we want to build them without CONFIG_OF.
