net: stmmac: dwmac_socfpga: This platform has GMAC

Indicate that dwmac_socfpga has a gmac. This will make sure that
gmac-specific interrupt processing is done, including timestamp
interrupt handling. Without this, the external snapshot interrupt is
never ack'd and we have an interrupt storm on external snapshot event.
