Add devicetree file for the Exynos 4210 based Galaxy S2 (i9100
version).
Thanks for the patch!
It is an GT-I9100.

I think it shares a lot with Trats board...
Marek, how similar these
designs are? Maybe it is worth to split some parts and make common
part?

This looks like a stub/fake regulator. Probably it shoould be replaced
with proper regulator coming from PMIC (few seems to be missing
there).
I don't have the schematics so I cannot judge... I see Trats has the
same.
Marek, mayybe you know, is it really a separate regulator?
