mb/google/hatch/variants/hatch: Set PCH Thermal Threshold value to 77 deg 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=133345634 BRANCH=None TEST=Verified Thermal Device (B0: D20: F2) TSPM offset 0x1c [LTT (8:0)] value is 0xFE on Hatch.
