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.
