fsg-setup.c should use new style i2c model

RTC drivers were updated to the new style i2c model.

fsg-setup.c for Freecom FSG-3 was to date not updated to use it. Because of this, it is not possible to use the RTC.

This tiny patch updates arch/arm/mach-ixp4xx/fsg-setup.c to use the correct device.

It also removes an unused variable which was issuing a compilation warning.
