IIO channel type and modifiers for CCT and RGBC data
Add iio channel type and modifiers for Correlated Color Temperature (CCT) and RGBC (red/green/blue/clear) data. Add CCT and RGBC descriptions to documentation. Changes: Revised/condensed RGBC descriptions. Merge and trivial fix done by Jonathan Cameron. Signed-off-by: Jon Brenner <jbrenner@taosinc.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

+Description:
+ This property is supported by sensors that have a RGBC
+ sensing mode. This value should be the output from a reading
+ and if expressed in SI units, should include _input. If this
+ value is not in SI units (irradiance, uW/mm^2), then it should
+ include _raw.

+Description:
+ This should return the correlated color temperature from the
+ light sensor. If it comes back in SI units, it should also
