From: Igor Opaniuk <igor.opaniuk@toradex.com>

Introduce DTS for Colibri iMX6S/DL V1.1x re-design, where UHS-I support was
added. Provide proper configuration for VGEN3, which allows that rail to
be automatically switched to 1.8 volts for proper UHS-I operation mode.

v3:
- change hierarchy according to Marco's suggestions [Marco Felsch]
- adjust compatible string adding v1.1 [Stefan Agner]

v2:
- rework hierarchy of dts files, and a separate dtsi for Colibri
  iMX6S/DL V1.1x re-design, where UHS-I was added [Marcel Ziswiler]
- add comments about vgen3 power rail [Marcel Ziswiler]
- fix other minor issues, addressing Marcel's comments. [Marcel Ziswiler]
