 * @i2c: The platform data to set, or NULL for default data.
 *
 * Register the given platform data for use with the i2c0 device. This
 * call copies the platform data, so the caller can use __initdata for
 * their copy.
 *
 * This call will set cfg_gpio if is null to the default platform
 * implementation.
 *
 * Any user of s3c_device_i2c0 should call this, even if it is with
 * NULL to ensure that the device is given the default platform data
 * as the driver will no longer carry defaults.
