thermal/drivers/qcom/tsens: Widen temperature limits to match hardware range

Browse Source 
The TSENS v2 software driver currently clamps trip_min_temp and
trip_max_temp to -40°C and 120°C respectively. However, the
TSENS v2 hardware temperature threshold registers support a wider
programmable range from -204°C to +204°C.

On newer chipsets using TSENS v2, devices may legitimately operate
beyond the existing software limits (for example, up to 130°C). When a
trip temperature is programmed outside the software clamped range, it is
constrained to 120°C on the upper end or -40°C on the lower end.
If the actual temperature continues to exceed this clamped limit, the
threshold is immediately violated again, which can result in a
continuous interrupt storm.

Expand the TSENS v2 software trip temperature limits to match the full
hardware supported range (-204°C to +204°C). This avoids repeated
threshold reprogramming and ensures correct trip handling on TSENS v2
based platforms.
