[PATCH v1 07/14] ARM: dts: imx6ull-colibri: update device trees to support overlays

From: Denys Drozdov <denys.drozdov at toradex.com>
Prepare in-tree device trees for out-of-tree device tree overlay support
(eMMC SKU only).
Relocate panel-dpi default to edt,et057090dhu (RGB 18bit VGA 640x480)
to the module-level dtsi and remove it from the carrier board dtsi.
Keep backlight, resistive touch and Atmel maxtouch nodes enabled
for both eMMC and NAND modules.
