The panel is a LogicTechno LT161010-2NHR 7" WVGA TFT Transmissive LCD with a resistive touch. The overlay content is identical to the Colibri iMX7 eMMC one. To avoid duplicating it, rework the Colibri iMX7 eMMC overlay moving its content to a new dtsi shared between the two modules, and include it from both overlays. The overlay is also combined with the Eval carrier board device tree to provide a ready-to-use DTB.
