[PATCH v4 2/2] ARM: dts: colibri: introduce dts with UHS-I support enabled

[Igor Opaniuk]

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.
