Liu Peibao 2ae34111fe stmmac: dwmac-loongson: fix invalid mdio_node
In current code "plat->mdio_node" is always NULL, the mdio
support is lost as there is no "mdio_bus_data". The original
driver could work as the "mdio" variable is never set to
false, which is described in commit <b0e03950dd71> ("stmmac:
dwmac-loongson: fix uninitialized variable ......"). And
after this commit merged, the "mdio" variable is always
false, causing the mdio supoort logic lost.

Fixes: 30bba69d7db4 ("stmmac: pci: Add dwmac support for Loongson")
