[POWERPC] mpc5200: Allow for fixed speed MII configurations

Browse source 
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

@ -237,6 +237,17 @@ Each GPIO controller node should have the empty property gpio-controller and
according to the bit numbers in the GPIO control registers. The second cell
is for flags which is currently unsused.
8) FEC nodes
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
speed. This property should contain two cells. The
first cell specifies the speed in Mbps and the second
should be '0' for half duplex and '1' for full duplex
"phy-handle" - Contains a phandle to an Ethernet PHY.
