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.
