[PATCH] tegra20: add generic board

[PATCH] tegra20: add generic board

[Lucas Stach]

The Tegra arch will be fully based on device tree and most boards
shouldn't need anything more than the generic drivers and arch code.

Define a dummy board entry and generic defconfig as a strting point for
building a board with DT support.
