Would it make sense to split out the parts that are common with A13 into
a separate sun5i.dtsi file?

I don't have the documentation at the moment, so I'm not exactly sure at
which extent it's similar to the A13. Yet for the moment, the two dtsi
are very different (different clock definitions, different muxings,
etc.), so , I'm not quite sure about wether it would make stuff smaller.

Of course, if we find they actually share a lot, we can definitely make
a common sun5i DTSI later.

But if you prefer to have it right now, I can always send a v2 :)

I thought it was actually the same silicon in a different package with
fewer pins, but if the files look very different right now, just leave
them separately.
