google/panther: Avoid shutdown when thermal sensor is unavailable
When the thermal sensor on Panther is unavailable (early on resume)
it will return 0x80 which causes our AML thermal code to overflow,
which causes the system to shut down. Instead, return a reasonable
value in those cases so that the system will continue running until
the sensor gets back on its feet.
