ACPI: thermal: Do not attach private data to ACPI handles
The ACPI thermal driver uses acpi_bus_attach_private_data() to attach the thermal zone object to the ACPI handle of the thermal zone and acpi_bus_detach_private_data() to clean that up, but it never uses acpi_bus_get_private_data() to retrieve that object. Drop the unneded acpi_bus_attach_private_data() and acpi_bus_detach_private_data() calls from the ACPI thermal driver and clean up the related code. No intentional functional impact.
