[U-Boot] [PATCH 07/17] 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.
