drm/panel: y030xx067a: Make use of the helper function dev_err_probe()
When possible use dev_err_probe help to properly deal with the PROBE_DEFER error, the benefit is that DEFER issue will be logged in the devices_deferred debugfs file. And using dev_err_probe() can reduce code size, the error value gets printed.
