I debated if it was more appropriate to:

1. make a duplicate in each ethernet node (ethernet0/1)
2. Put it in one and reference from both
3. have it floating around independent like this, similar to what is
done in sa8155p-adp.dts[0]

I chose 3 as it seemed cleanest, but if there's a good argument for a
different approach I'm all ears!
