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.
