net: Allow network devices to have PHY statistics
Add a new callback: get_ethtool_phy_stats() which allows network device drivers not making use of the PHY library to return PHY statistics. Update ethtool_get_phy_stats(), __ethtool_get_sset_count() and __ethtool_get_strings() accordingly to interogate the network device about ETH_SS_PHY_STATS.
