It's possible to have a rest-gpios property both in the mdio node and 
the phy node. The former resets the whole bus while the later a single 
PHY, at least that's my understanding.

I think it would be more correct to move the reset-gpios up one level 
for r8a779g0. However as it already was in the PHY node and this 
functioned as it should I kept it there.

The need for the mdio node was to avoid a device specific property added 
in the BSP to reset the whole bus. At the moment I can't recall the two 
different call sites for when the two resets are called. Maybe if we 
move it to the mdio node we can avoid setting the PHY id in the 
compatible string as we could then always probe the PHY correctly. I 
will look into it.
