ec/google/wilco/acpi: Add DPTF support
Add the support needed for DPTF. This includes the methods to write trip point values, read temperatures, and handle events. This was tested on a sarien board by inspecting AML debug output with the kernel while monitoring temperatures and trip points in sysfs and controlling temperatures with a fan to ensure that when a trip point is crossed an SCI is generated and the event is handled properly.
