Now i'm very sure the old binding is incorrect. I've downloaded TRM for 
Hi3516DV300. And found that it is, in fact, very similar to Hi3798MV200. 
There is no dedicated MDIO bus clock. the MDIO bus clock is always 
provided by the MAC controller. So here i can say MDIO bus is always 
integrated into the FEMAC Ethernet controller, not the SoC.


Maybe someday we can merge these two drivers together later. We don't 
need a MDIO bus node at all!
