[U-Boot] [PATCH 9/9] sunxi: Enable EMAC on the Bananapi M3

[Chen-Yu Tsai]

The Bananapi M3 has an RTL8211E PHY connected to the EMAC using
RGMII. The PHY is powered by DCDC1 through SW @ 3.3V.

This patch adds a U-boot specific dtsi file for the board adding
an enabled EMAC node, and enables the EMAC driver in the defconfig.
The binding used here is the old revision currently supported in
U-boot. There is no stable binding nor support in upstream Linux
at this time.
