ACPI: thermal: Add device list to struct acpi_thermal_trip

Browse Source 
The device lists present in struct acpi_thermal_passive and struct
acpi_thermal_active can be located in struct acpi_thermal_trip which
then will allow the same code to be used for handling both the passive
and active trip points, so make that change.

No intentional functional impact.
