usb: xhci: Implement update_hub_device() operation

There is no way to know whether the attached device is a hub or
not in advance before the device's descriptor is fetched. But
once we know it's a high speed hub, per the xHCI spec, we need
to tell xHC it's a hub device by initializing hub-related fields
in the input slot context.
