thermal/drivers/hisi: Remove thermal data back pointer
The presence of the thermal data pointer in the sensor structure has the unique purpose of accessing the thermal data in the interrupt handler. The sensor pointer is passed when registering the interrupt handler, replace the cookie by the thermal data pointer, so the back pointer is no longer needed.
