tegra250.dts describes everything within the Tegra SoC, but leaves all
optional devices disabled.
tegra-harmony.dts is now the configuration of the SoC for the board,
i.e. it enables the optional devices that are required for the board,
and provides any required platform data for those devics.
The prevents every Tegra board having to repeat all the basic internal
SoC wiring.

v2: Rebased on latest devicetree/test; incorporated changes from there
into the new tegra250.dts.
