Add property enet-phy-lane-order to the device tree bindings to define the lane order of the PHY. To simplify PCB design some manufacturers allow to wire the pairs in a reverse order, and change the order in software. The property can be set to 0 to force the normal lane order (ABCD), or 1 to force the reverse lane order (DCBA).
