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.

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
