[POWERPC] mpc5200: Allow for fixed speed MII configurations
Various improvements for configuring the MPC5200 MII link from the device tree: * Look for 'current-speed' property for fixed speed MII links * Look for 'fsl,7-wire-mode' property for boards using the 7 wire mode * move definition of private data structure out of the header file Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfgang Grandegger <wg@grandegger.com>

+The FEC node can specify one of the following properties to configure
+the MII link:
+"fsl,7-wire-mode" - An empty property that specifies the link uses 7-wire
+ mode instead of MII
+"current-speed" - Specifies that the MII should be configured for a fixed

+"phy-handle" - Contains a phandle to an Ethernet PHY.
