drm/imx: parallel-display: check return value of devm_drm_bridge_add() in imx_pd_probe()
Return the value of devm_drm_bridge_add() in order to propagate the
error properly, if it fails due to resource allocation failure or bridge
registration failure.
This ensures that the probe function fails safely rather than proceeding
with a potentially incomplete bridge setup.
