Because patched if_arge use it only with sc->arge_mac_unit, which is 0
for arge0, and 1 for arge1.

So there is two ways:
1. Just remove unit argument. 
"ARGE_MII_READ(AR71XX_MAC_MII_INDICATOR)" instead of
"ARGE_MII_READ(sc->arge_mac_unit,AR71XX_MAC_MII_INDICATOR)"
2. or remove it completely, since for that case
ARGE_READ/ARGE_WRITE will do the same.

But if you will use here another variable, (f.e. 
sc->arge_mdio_unit or sc->arge_mii_unit), then it would have sense.
Then you will be able to set it from hints and default to
sc->arge_mac_unit otherwise.
