ethtool: drop get_settings and set_settings ops

As Andrew Lunn pointed out in recent discussion, there is only one in tree driver left which still defines deprecated callbacks get_settings() and set_settings() in ethtool_ops. First patch converts this driver to get_link_ksettings() and set_link_ksettings(). Second patch then removes the deprecated callbacks from struct ethtool_ops and ethtool code which falls back to them.

This doesn't break old versions of ethtool or any other userspace code using ETHTOOL_{G,S}SET. We still implement both (old) ETHTOOL_{G,S}SET and (new) ETHTOOL_{G,S}LINKSETTINGS ioctl commands but after this series both will be implemented only using {g,s}et_link_ksettings(). The only affected code would be out of tree NIC drivers which have not been converted yet.
