mb/google/poppy/variants/nami: Tune Fan speed
Tuning of fan speed for different temperature values. Earlier while running few benchmarks, fan was always getting on and starting at higher speed. With this change fan will start with lower speed and slowly speed gets increased if temperature continue going high. Thermal team provided these data after fine tuning of fan speed. BUG=None. TEST=Verified on Nami running with different benchmarks and observed fan speed.
