net: stmmac: sun8i: add support for Allwinner H6 EMAC 



The EMAC on Allwinner H6 is just like the one on A64. The "internal PHY" on
H6 is on a co-packaged AC200 chip, and it's not really internal (it's
connected via RMII at PA GPIO bank).

Add support for the Allwinner H6 EMAC in the dwmac-sun8i driver.
