[PATCH v3 08/13] ARM: dts: imx6ull-colibri: add support for toradex iris carrier boards

[Marcel Ziswiler <marcel@ziswiler.com>]

From: Denys Drozdov <denys.drozdov@toradex.com>

Add support for Toradex Iris, small form-factor Pico-ITX Colibri Arm
Computer Module family carrier boards.

Iris Device Trees:
- imx6ull-colibri-iris.dtb
- imx6ull-colibri-emmc-iris.dtb
- imx6ull-colibri-wifi-iris.dtb

Iris-V2 Device Trees:
- imx6ull-colibri-iris-v2.dtb
- imx6ull-colibri-emmc-iris-v2.dtb
- imx6ull-colibri-wifi-iris-v2.dtb

Changes in v3:
- Replaced underscores by dashes in GPIO hog node names.
- Added more LVDS specific GPIO hogs in-line with other modules.

Changes in v2:
- Fix alphabetical node order as suggested by Shawn.
