soc/intel/skylake: Set low maximum temperature threshold for Thermal Device
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.
