ARM: dts: socfpga: sodia: Fix mdio bus probe and PHY address

Browse Source 
commit ea9da67e2add7bd5f1e4b38dc2404480e711f4d8 upstream.

On SoCFPGA/Sodia board, mdio bus cannot be probed, so the PHY cannot be
found and the network device does not work.

```
stmmaceth ff702000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19)
```

To probe the mdio bus, add "snps,dwmac-mdio" as compatible string of the
mdio bus. Also the PHY address connected to this board is 4. Therefore,
change to 4.
