[PATCH 1/2] ARM: DT: tegra: Add board level compatible properties

[Bryan Wu <pengw-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

The compatible properties of Tegra SoC based boards or machines need
to be documented. This patch adds these board levle compatible
properties into device tree binding document.
