ACPI: thermal: Register thermal zones without valid trip points

Some laptops where the thermal control is handled by the EC may
provide trip points that fail the kernels new validation, but still have
working temperature sensors. An example of this is the Framework 13 AMD.

This patch allows the thermal zone to still be registered without trip
points if the trip points fail validation, allowing the temperature
sensor to be viewed and used by the user.
