siemens/mc_bdx1: Initialize GPIOs
Add GPIO initialization for mc_bdx1 mainboard. Call init_gpios() as
early as possible as FSP will set up things (like hiding PCI devices)
rather early. If connections on the mainboard are dependent on GPIO
settings then FSP can screw things up (e.g. disabling not yet connected
PCI root ports).
