1. Introduce dtsi with overlay configuration for enabling UHS-I for Colibri iMX6S/DL V1.1x re-design. 2. Introduce new dts for the Colibri iMX6S/DL V1.1x on Colibri Evaluation Carrier Board V3.x. However, disable 1.8V for the Colibri Evaluation Board since this carrier board has 3.3V pull-ups on. 3. Provide proper configuration for VGEN3, which allows that rail to be automatically switched to 1.8 volts for proper UHS-I operation mode.
