[PATCH v2 0/5] ARM: dts: sunxi: Remove unused address-cells/size-cells of dwmac-sun8i

[Corentin Labbe]

address-cells/size-cells is unnecessary for dwmac-sun8i node.
It was in early days, but since a mdio node is used, it could be
removed.

This patch fix the following DT warning:
Warning (avoid_unnecessary_addr_size): /soc/ethernet@1c50000: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
