In order to use the generic thermal trips which is a simple array, let's move out those fields in the struct acpi_thermal instead of having them encapsulated in an intermediate structure. No functional changes, just simplification of code.

Initialize the trip points by reading the ACPI table and then doing a check trip points exists. This check will go through all the trip points and at the end if a valid trip point is found, the parsing is considered valid. Instead of checking all the trip points, exit when a valid trip point is found.

In order to improve its readability, let's encapuslate the different parts into dedicated functions. So we can act individually per trip type changes and will make easier to review the next changes.
