ec/lenovo/h8/acpi/thermal: Add support for passive cooling
The ACPI spec requires _TSP, _TC1, _TC2 and _PSL for passive cooling. _TSP already has been added in a previous commit. Copy the coefficients used on google devices to activate the feature and add _PSL for SandyBridge, IvyBridge and IbexPeak based Thinkpads.
On older Thinkpads the PPKG method needs to be implemented first.
Tested on Lenovo T430: The CPU is throttled once the passive threshold has been reached.
