mb/google/guybrush: Initialize WWAN for USB if requested
To set the Fibocom 850-GL module to USB mode, it needs to be disabled when PCIe training happens, or it will automatically switch to PCIe mode. This patch makes sure it's shut down when training happens in FSP-M. It will be brought up in ramstage and will be available for USB enumeration later. BUG=b:187316460 TEST=Run lsusb from the OS and see that the Fibocom module is present on USB.
