The hw_id field in 'struct tsens_sensor' can do the job of tracking
unique ids for each sensor connected to each tsens device instance. It
also allows hw_ids to be overridden (e.g. 8916) in cases where some
sensors in a sequence are disabled on a particular platform.
Use the hw_id field instead of the id field consistently across the
tsens code.
While we're at it, document the fields of struct tsens_sensor.
