Rather than add that as a separate node at the top-level, I think just
add another sub-node to the "regulators" node. Oh, in fact it's already
there in next-20120816; you just need to add a label.

It's pretty trivial I know, but I'd almost be tempted to make that a
separate patch so that it could be cherry-picked somewhere without a
tegra20-ventana.dts. But, perhaps that's silly.
