Allwinner V3s SoC has an Ethernet MAC and an internal PHY like the ones in H3 SoC, however the MAC has no external *MII interfaces available at GPIOs, thus only MII connection to internal PHY is supported. Add this variant of EMAC to dwmac-sun8i driver. The default value of the syscon EMAC-related register seems to have changed from H3, but it seems to be a harmless change.
