[PATCH 2/3] ARM: dt: tegra: ventana: add regulators

[Stephen Warren <swarren-3lzwWm7+Weoh9ZMKESR00Q@public.gmane.org>]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Ventana uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.

The regulator configurations were all taken from NVIDIA's downstream
android-tegra-nv-3.1 kernel.
