nicole: Update DTS

Prepares the Nicole DTS to push it to the linux mainline.

 - Removes unused i2c buses.
 - Adds a comment for empty i2c definitions.
 - Adds a missed iio-hwmon-battery node.
 - Adds the GPIOs names.
 - Adds the leds labels.

(From meta-yadro rev: ae1aea75fe6b5369183b86a05729d56abec77565)
