From: Manaf Meethalavalappu Pallikunhi <quic_manafm@quicinc.com>
The sm8750 includes four TSENS instances, with a total of 47 thermal
sensors distributed across various locations on the SoC.
The TSENS max/reset threshold is configured to 130°C in the hardware.
Enable all TSENS instances, and define the thermal zones with a hot trip
at 120°C and critical trip at 125°C.
