usb: Add an interval parameter to create_int_queue
Currently create_int_queue is only implemented by the ehci code, and that does not honor interrupt intervals, but other drivers which might also want to implement create_int_queue may honor intervals, so add an interval param. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
