[PATCH 2/2] thermal: intel_pch_thermal: Add critical callback to override default shutdown behavior

[Kai-Heng Feng <kai.heng.feng@canonical.com>]

Like previous patch, the intel_pch_thermal device is not in ACPI
ThermalZone namespace, so a critical trip doesn't mean shutdown.

Override the default .critical callback to prevent surprising thermal
shutdoown.
