This adds a phy_ethtool_get_link() function along the same lines as
phy_ethtool_gset(). This provides drivers utilizing PHYLIB an
alternative to using ethtool_op_get_link(). This is more desirable
since the "Link detected" field in ethtool would actually reflect the
state of the PHY register.
Patch depends on previous patch (0/2).
