T60: Add support for Ultrabay Legacy I/O devices (40Y8122)
Those modules have basically the same Super I/O capabilities as the Docking station. Unfortunately, the Super I/O in the module shares the same I/O address as the Docking station, so we're not allowed to connect the LPC Docking Bus if such a module is present. To be able to detect this device and use it as early console for coreboot, we have to initialize the GPIO Controller before, as this device is detected via GPIO06.
