Add an u64 hardware timestamping statistics structure for each ocelot port. Export a function from the common switch library for reporting them to ethtool. This is called by the ocelot switchdev front-end for now. Note that for the switchdev driver, we report the one-step PTP packets as unconfirmed, even though in principle, for some transmission mechanisms like FDMA, we may be able to confirm transmission and bump the "pkts" counter in ocelot_fdma_tx_cleanup() instead. I don't have access to hardware which uses the switchdev front-end, and I've kept the implementation simple.
