[PATCH 2/2] net: cpsw: Set phy device_node pointer in probe

Set the phy device_node pointer to the equivalent cpsw slave node.
We need this, because phy drivers using this pointer for their configuration.

Create and register the phy device in cpsw_probe(), so that this phy device
can be found later by phy_device_connect() in cpsw_open().
