[PATCH net v1 2/2] net: phy: dp83tg720: get initial master/slave configuration

[Oleksij Rempel]

Get initial master/slave configuration, otherwise ethtool
wont be able to provide this information until link is
established. This makes troubleshooting harder, since wrong
role configuration would prevent the link start.
