This is a general update of the Colibri iMX6 device tree files.

The Toradex Colibri family is composed of a SoM that can be plugged on
various carrier boards, with carrier boards allowing multiple optional
accessories (e.g. display, camera, ...).

The device tree sources are structured into a SoM dtsi and a carrier dts
which then includes the SoM dtsi. The SoM dtsi defines and enables the
functionality self contained on the SoM and prepares for functionality
provided by the carrier HW or accessories, so that the carrier dts then
can enable or amend nodes provided. Accessories are enabled in overlays
depending on HW configuration.

The series improves the existing Colibri Evaluation Board device tree and
adds new device trees for the Aster, Iris, and Iris V2 carrier boards.

Additionally it drops the dedicated device tree for SoM V1.1 HW used in a
Evaluation board. The regular device tree works well in that combination.
The higher SD card speed possible with SoM V1.1 would require HW
modification on the carrier board.

Improvements:
- Specifies GPIO line names for use with libgpiod.
- Disables optional accessories. They would be enabled in overlays
depending on HW configuration.
- Lower power consumption after poweroff.
- Move more functionality into the SoM dtsi file to reduce code
duplication.
- General cleanup to adhere to dtbs bindings and missed alphabetically
ordering.

Fixes:
- Copy/paste error in i2c2 pinmuxing resulting in i2c2 being
nonfunctional.

Adds:
- imx6dl-colibri-aster.dtb: used for a Colibri iMX6 mated in an Aster
carrier board.
- imx6dl-colibri-iris.dtb: used for a Colibri iMX6 mated in an
Iris V1.x carrier board.
- imx6dl-colibri-iris-v2.dtb: used for a Colibri iMX6 mated in an
Iris V2.x carrier board.

Drops:
- imx6dl-colibri-v1_1-eval-v3.dtb, imx6dl-colibri-eval-v3.dtb is good
enough.

Changes in v2:
- Addressed 'From' address as reported by checkpatch / Shawn's feedback.
- Added Rob's Ack to the 'dt-bindings' patches.
