net: mscc: ocelot: add TX timestamping statistics
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.
