board: ti: am33xx: Add Ethernet support for Beaglebone Green Eco
Currently, the Ethernet interface of the BBGE board isn't properly
supported.
To support this interface, describe the MAC<->PHY RGMII link and the
DP83867 PHY in the BBGE device tree. Enable the DP83867 PHY driver in
U-Boot Proper and mux the relevant RGMII lines.
