Merge branch 'net-phy-Uninline-PHY-ethtool-statistics'

Florian Fainelli says:

====================
net: phy: Uninline PHY ethtool statistics

Now that we have introduced ethtool_phy_ops we can uninline those
operations and move them back into phy.c where they belong. Since those
functions are used by DSA, we need to continue exporting those symbols.

It might be possible to remove ndo_get_ethtool_phy_stats in a subsequent
patch since we could have DSA register its own ethtool_phy_ops instance
instead of overloading the ethtool_ops.
