Mmh, I find examples for both ways (.dtsi vs. .dts) in the kernel. I
need to learn what's the best practice here.

But the U-Boot DTs need to get replaced anyway soon-ish, since the Linux
DTs (which are WIP) have already diverged.
So what about we keep this alias here next to the existing one for the
2016.11 release and possibly fix this later once we replace the DTs
anyway with what gets merged into the kernel eventually?

In the end of the day it's an easy and obvious fix which makes many
people happy (since it allows TFTP boot of the Pine64).

Cheers,
Andre.
