Ethtool callbacks {get|set}_link_ksettings are often the same, so
we add two generics functions phy_ethtool_{get|set}_link_ksettings
to avoid writing severals times the same function.

The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the one
contained in struct net_device.

There are two generics functions phy_ethtool_{get|set}_link_ksettings,
so we can use them instead of defining the same code in the driver.
