gpio: omap: handle deferred probe with dev_err_probe() for gpiochip_add_data()

Browse Source 
The gpiochip_add_data() may return -EPROBE_DEFER which is not handled
properly by TI GPIO driver and causes unnecessary boot log messages.

Hence, add proper deferred probe handling with new dev_err_probe() API.
