net: mvpp2: add support for hardware timestamps
Add support for hardware timestamps in (e.g.) the PHY by calling
skb_tx_timestamp() as close as reasonably possible to the point that
the hardware is instructed to send the queued packets.
As this also introduces software timestamping support, report those
capabilities via the .get_ts_info() method.
