VBUS detection could be needed not only by the musb code (to prevent host mode), but also by e.g. gadget drivers to start only when a cable is connected. In addition, this allows more flexibility in vbus detection, as it could easily be extended to other USBC indexes. Eventually, this would help making musb support independent from a hardcoded USB controller index (0).
