Add support for color light sensor presented by the Chromebook Embedded Controller (EC). Instead of just presenting lux measurement (clear channel), a color light sensor is able to report color temperature measurement.
The EC, using factory settings, can transform the raw measurement into the CIE 1931 XYZ color space (XYZ) and take adavantage of color sensor autocalibration to provide the most accurate measurements.
