net: sparx5: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()

The hardware timestamping through ndo_eth_ioctl() is going away.
Convert the sparx5 driver to the new API before that can be removed.

After removing the timestamping logic from sparx5_port_ioctl(), the rest
is equivalent to phy_do_ioctl().
