i2c: i2c_gpio: keep probe resident for hotplugged devices.
Change the i2c_gpio driver to use platform_driver_register() instead of platform_driver_probe() to ensure that is can attach to any devices that may be loaded after it has initialised. Acked-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
