This was because the sensors connected to a TSENS IP might not be contiguous i.e. 1, 2, 4, 5 with 3 being skipped. This causes confusion in the code which uses hw_id sometimes and id other times (tsens_get_temp, tsens_get_trend). Switch to only using the hw_id field to track the physical ID of the sensor. When we iterate through all the sensors connected to an IP block, we use an index i to loop through the list of sensors, and then return the actual hw_id that is registered on that index.
