Clean-up imx_v6_v7_defconfig and then add support for the new Colibri
iMX6ULL 1GB (eMMC) which builds on the success of the existing Colibri
iMX6ULL SKUs using raw NAND but replaces this with more RAM (1 GB) and
an eMMC (4 GB).

Changes in v2:
- New patch cleaning-up dt-bindings documentation.
- Fix indentation.
- Use latest agreed upon SPDX-License-Identifier GPL-2.0+ OR MIT.
- Drop AG in our copyright statement as recommended by our legal.
- New patch documenting dt-bindings.

Add a device tree for a Colibri iMX6ULL 1GB which has a eMMC instead of
the raw NAND used on other SKUs.
