Subject: [PATCH net-next v2 5/9] fs_enet: use the new fixed PHY helpers

of_phy_connect_fixed_link() is becoming obsolete, and also required
platform code to register the fixed PHYs at the specified addresses for
those to be usable. Get rid of it and use the new of_phy_is_fixed_link()
plus of_phy_register_fixed_link() helpers to transition over the new
scheme.

- merge if conditions on the same line as suggested by Sergei
- add comment explaining the device_node pointer assignment
