[U-Boot] [PATCH 3/4] sunxi: add stub EMAC device node in A83T device tree

[Icenowy Zheng]

The Allwinner A83T SoC has an EMAC which is already supported by
sun8i_emac driver in U-Boot now.

Add a stub device node for it.

The device node cannot work for Linux, because it now lacks the proper
clock definition; however, it can satisfy sun8i_emac driver in U-Boot.
