stmmac: Stop advertising 1000Base capabilties for non GMII iface (V4).

Browse source

This patch stops advertising 1000Base capablities if GMAC is either
configured for MII or RMII mode and on board there is a GPHY plugged on.
Without this patch if an GBit switch is connected on MII interface,
Ethernet stops working at all.
