net: mv643xx_eth: Fetch the phy connection type from DT

Browse Source 
The MAC is capable of RGMII mode and that is probably a more typical
connection type than GMII today (eg it is used by Marvell Reference
designs for several SOCs). Let DT users specify the standard

   phy-connection-type = "rgmii-id";

On a phy node.
