[PATCH v2 9/9] ARM: dts: imx7: add Toradex Colibri iMX7D 1GB (eMMC) support

[Stefan Agner <stefan@agner.ch>]

Add support for the Computer on Module Colibri iMX7D 1GB along
with the Colibri Evaluation Board device trees. Follow the usual
hierarchic include model, maintaining shared configuration in
imx7-colibri.dtsi and imx7-colibri-eval-v3.dtsi respectively.
