drm/imx: parallel-display: Accept drm_of_find_panel_or_bridge failure
commit 799ee297 upstream. The parallel panel driver should continue to work without having an endpoint linking to an panel in DT for backwards compatibility. With the recent switch to drm_of_find_panel_or_bridge, an absent panel results in a failure with -ENODEV error return code. To restore the old behaviour, ignore the -ENODEV return code.
