These modules need to depend on iic, not just on i2cexec. (They will
still recursively get i2cexec since the iic depends on it.)

A driver for the Sensirion SGP40 MOx gas sensor. An example of this
chip from Adafruit is:
https://www.adafruit.com/product/4829
This is a moderately priced gas sensor that can detect volatile
organic compounds in the air. The driver uses the 3-clause BSD
licensed VOC algorithm provided by Sensirion to turn the raw sensor
metric into a VOC index which can indicate the quality of the air in a
particular indoor environment. All published functions of the chip
are supported and one unpublished feature.
