mb/google/poppy/variants/soraka: Set PCH thermal trip point to 75 degreeC
PMC logic shuts down the thermal sensor when CPU is in a C-state and DTS Temp <= Low Temp Threshold in case Dynamic Thermal Shutdown in S0ix is enabled. BUG=b:69110373 BRANCH=none TEST=Ensure Thermal Device(B0: D20: F2) TSPM offset 0x1c[LTT (8:0)] value is 0xFA.
