[PATCH v2 2/3] ARM: DT: tegra: Add Colibri T20 512MB COM

[Lucas Stach <dev-8ppwABl0HbeELgA04lAiVw@public.gmane.org>]

This adds the device tree include file for the Toradex Colibri T20
Computer on Module (COM). It's only valid for the 512MB RAM version of
the module, as the 256MB version needs different EMC tables and flash
configuration. To make this clear the suffix -512 was added to the board
compatible string.

The Colibri T20 uses a Tegra2 SoC and has onboard USB Ethernet and AC97
sound.

Still some things like onboard NAND support missing, but should be a
good base for further development.

v2:
- remove some whitespace
- remove nodes that don't carry any additional info
- unify regulator node between module and carrier board
