[POWERPC] FSL: enet device tree cleanups

* Removed address fields in ethernet nodes
* Removed #address-cells, #size-cells from gianfar nodes
* Added cell-index to gianfar and ucc ethernet nodes
* Added enet[0..3] labels
* Renamed compatible node for gianfar mdio to "fsl,gianfar-mdio"
* Removed device_type = "mdio"

The matching for gianfar mdio still supports the old "mdio"/"gianfar" combo
but it is now considered deprecated.

   Required properties:
     - reg : Offset and length of the register set for the device
-    - device_type : Should be "mdio"
     - compatible : Should define the compatible device type for the
-      mdio.  Currently, this is most likely to be "gianfar"
+      mdio.  Currently, this is most likely to be "fsl,gianfar-mdio"
