soc/intel/common/block: Enable PCH Thermal Sensor for threshold configuration
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: D18: F0) TSPM offset 0x1c [LTT (8:0)]
value is 0xFE.
