Use USB hub device's dev->uclass_priv to point to 'usb_hub_device' so that with driver model usb_hub_reset() and usb_hub_allocate() are no longer needed.

Can you trim down the ifdeffery somehow or keep it more contained ? I don't like having the code polluted by ifdefs all over the place, so maybe factor out the specialties into function and put ifdef around that or somesuch.
