====================
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.
