Bug description:
[Impact]
Surprising thermal shutdown at boot on Intel based mobile workstations.
[Fix]
Since these thermal devcies are not in ACPI ThermalZone, OS shouldn't
shutdown the system.
These critial temperatures are for usespace to handle, so let kernel
know it shouldn't handle it.
SRU for stable kernels will be sent after the fix is in upstream.
[Test]
Use reboot stress as a reproducer. 5% chance to see a surprising
shutdown at boot.
With the fix applied, the thermal shutdown is no longer reproducible.
[Where problems could occur]
For ACPI based platforms, we still have "acpitz" to protect systems from
overheating. If these acpitz sensors don't work, then the system could
face real overheating issue.
