net: ethtool: allow MAC drivers to override ethtool get_ts_info
Check whether the MAC driver has implemented the get_ts_info()
method first, and call it if present. If this method returns
-EOPNOTSUPP, defer to the phylib or default implementation.
XXX: review any drivers that use phylib and provide get_ts_info().
