staging: ccree: Convert to platform_{get,set}_drvdata()
Platform devices are expected to use wrapper functions, platform_{get,set}_drvdata() with platform_device as argument, for getting and setting the driver data. dev_{get,set}_drvdata() are using &plat_dev->dev. For wrapper functions we can directly pass a struct platform_device. dev_set_drvdata() is redundant and therefore removed. The driver core clears the driver data to NULL after device_release or on probe failure.
