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.
