drm/imx: parallel-display: Accept drm_of_find_panel_or_bridge failure

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.
