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 Tegra20 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.

- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups,
a few __init annotation fixes and some error handling improvement
in their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2

- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning

All in all a bit more positive code delta than we'd ideally want to see

We originally thought that the MV78230 variant of the Armada XP had
four Ethernet interfaces, like the other variants MV78260 and

Ethernet interfaces.
So, the definitions of the Ethernet interfaces is now done as follows:
* armada-370-xp.dtsi: definitions of the first two interfaces, that
are common to Armada 370 and Armada XP
* armada-xp.dtsi: definition of the third interface, common to all
