Revert "iio: hid-sensor-als: Add light color temperature support"

Browse Source 
This reverts commit 5f05285df6.

This commit assumes that every HID descriptor for ALS sensor has
presence of usage id ID HID_USAGE_SENSOR_LIGHT_COLOR_TEMPERATURE.
When the above usage id is absent,  driver probe fails. This breaks
ALS sensor functionality on many platforms.

Till we have a good solution, revert this commit.
