pc8736x_gpio: use platform_device_unregister in pc8736x_gpio_cleanup()
platform_device_unregister() only calls platform_device_del() and platform_device_put(), thus use platform_device_unregister() to simplify the code. Also the documents in platform.c shows that platform_device_del and platform_device_put must _only_ be externally called in error cases. All other usage is a bug. dpatch engine is used to auto generate this patch.
