Two different set_mac functions exists but stmmac_dwmac4_set_mac() is only used for enabling and never for disabling. So on dwmac4, the MAC RX/TX is never disabled. This patch add a generic function pointer set_mac() to stmmac_ops and replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to this pointer. Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops is duplioacted like dwmac4_dma_ops.
