mb/google/sarien/variants/sarien: Set PCH Thermal Trip point to 75 degree C

PMC logic shuts down the PCH thermal sensor when CPU is in a C-state and
DTS Temp <= Low Temp Threshold (LTT) in case of Dynamic Thermal Shutdown
when S0ix is enabled.

BUG=None
BRANCH=None
TEST=Verified Thermal Device (B0: D20: F2) TSPM offset 0x1c [LTT (8:0)]
value is 0xFA.
