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.
