usb: Add an usb_device parameter to usb_reset_root_port

Add an usb_device parameter to usb_reset_root_port so that it knows which
root-port it is resetting. This is necessary for proper device-model support
for usb_reset_root_port.

Also remove a duplicate declaration of usb_reset_root_port() from usb.h .
