Subject: [PATCH v2 02/11] thermal/acpi: Change to a common acpi_thermal_trip structure

The acpi trip point definition are very similar whatever their
types. Instead of creating a different structure for each trip type,
let's define and use a common one.

With this change we move a step forward to the generic trip point.

No functional changes.
