Allows detection of RGBC sensing devices such as the apds9960 by checking for the in_intensity_clear_ property, which reports the unprocessed lux value for the ALS photodiode. More information on the field can be found in the kernel iio docs: https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-bus-iio. Tested on a MSHW1084, which is compatible with te apds9960. The apsd9960 reference can be found here: https://docs.broadcom.com/doc/AV02-4191EN.
