[PATCH 5/6] sh_eth: remove custom .get_link_ksettings from ethtool ops

[Vladimir Zapolskiy <vladimir_zapolskiy@mentor.com>]

The change replaces a custom implementation of .get_link_ksettings
callback with a shared phy_ethtool_get_link_ksettings(), note that
&priv->lock wrapping is not needed, because the lock does not
serialize access to phydev fields.
