This -u-boot.dtsi was just a preliminary kludge until the official Linux
Ethernet support was merged.
I was hoping for getting this still into the release, since it's an easy
change and enables TFTP boot on the two boards (this patch here is just
preparation for the actual patch 2/6).

So the Linux Ethernet driver happened to be merged yesterday. \O/
I promise to update U-Boot's DTs with the kernel one's once we have at
least an -rc1 in the kernel (though this requires patch 6/6 in U-Boot).
This will then see these rgmii-emac.dtsi and the symlinks go away.

Cheers,
Andre.
