usb: Store bus type in usb_hcd, not in driver flags.
The xHCI driver essentially has both a USB 2.0 and a USB 3.0 roothub. So setting the HCD_USB3 bits in the hcd->driver->flags is a bit misleading. Add a new field to usb_hcd, bcdUSB. Store the result of hcd->driver->flags & HCD_MASK in it. Later, when we have the xHCI driver register the two roothubs, we'll set the usb_hcd->bcdUSB field to HCD_USB2 for the USB 2.0 roothub, and HCD_USB3 for the USB 3.0 roothub.
