ravb: make ravb_ptp_interrupt() *void*
When we have the ISS.CGIS bit set, we already know that gPTP interrupt has
happened, so an extra GIS register check at the end of ravb_ptp_interrupt()
seems superfluous. We can model the gPTP interrupt handler like all other
dedicated interrupt handlers in the driver and make it *void*.
