ACPI: thermal: Drop valid flag from struct acpi_thermal_trip
Notice that the valid flag in struct acpi_thermal_trip is in fact
redundant, because the temperature field of invalid trips is always
equal to THERMAL_TEMP_INVALID, so drop it from there and adjust the
code accordingly.
No intentional functional impact.
