I've noticed that you are using non DM I2C driver for IMX6Q. Was there
any reason not to use it?

> Changes in v3:
> - Correct spelling of Phytec
> - Remove unneeded license information
> - Correct image name in documentation
> - Correct whitespacing
> - Enable SPL to boot from MMC
> - Simplify defconfig, remove non-SPL build
