lantiq: add phy led config support over devicetree bindings

This patch adds the posibility to config the led behaviour of the lantiq phys
over the devicetree bindings.It patches the 0023-NET-PHY-adds-driver-for-lantiq-PHY11G
for 3.18 and 4.1. I have also added a register description overview for
applicable values. This goes to the documentation folder in the linux kernel.

++Lanitq PHY binding
++============================================

++		compatible = "lantiq,xrx200-mdio";
++			phy5: ethernet-phy@5 {

++			lantiq,led2h = <0x00>;
