ramips: ignore already handled ethernet phys

Browse Source 
The whole logic in fe_phy_connect() is based on the asumption that mdio
address and switch port id are equal. Albeit it is true for most
boards, it doesn't is for all.

It isn't yet clear which subtargets/boards require the devicetree less
ethernet phy handling. Hence change the code in a way that it doesn't
touch ethernet phys which were early attached and are already handled.
