  The temperature/humidity sensors of the STS3x/SHT3x family are
calibrated and factory-programmed with a unique serial number.
For some sensors, this serial number can be used to obtain a calibration
certificate via an API provided by the manufacturer (Sensirion).
Expose the serial number via debugfs.

Documentation is missing information about the sts3x support, add it.

Changelog
=========

v1 -> v2:
	- Change from sysfs to debugfs
	- Add documentation improvements

In v1 I stated that the serial number readout was not
documented for the whole SHT3x/STS3x series. I found that there is a
separate document for SHT3x documenting this feature.
For STS3x, the manufacturer confirmed with me that both families work
identically. Therefore, it is not needed to introduce more IDs than "sts3x"
and "sht3x", as they don't have different functionality.
