arm/dt: tegra devicetree support
Everything required to populate NVIDIA Tegra devices from the device
tree. This patch adds a new DT_MACHINE_DESC() which matches against
a tegra20 device tree. So far it only registers the on-chip devices,
but it will be refined in follow on patches to configure clocks and
pin IO from the device tree also.
