Add ACPI trip points parser helpers

Regarding thermal, the ACPI code parsing the trip points is duplicated inside different Intel drivers. The generic ACPI thermal driver also duplicates this code.

Those ACPI parsing actions are used to define trip points and these ones are defined by, and specific to, the backend driver.

The different get_trip_* ops, also very similar between each other, are using the specific trip point structure to return the requested trip point information.

From there, there is nothing new, all this can be converted to the generic trip point.

The first patch provides the functions to parse trip point description from the ACPI table but based on the generic trip point structure. The other patches convert the different Intel driver to use the ACPI functions along with a migration to the generic trip point.
