[PATCH v6 07/21] arm: sun8i: sunxi-h3-h5: add dwmac-sun8i ethernet driver

[Corentin Labbe]

The dwmac-sun8i is an ethernet MAC hardware that support 10/100/1000
speed.

This patch enable the dwmac-sun8i on Allwinner H3/H5 SoC Device-tree.
SoC H3/H5 have an internal PHY, so optionals syscon and ephy are set.
