thermal: intel: int340x: Add production mode attribute
It is possible that the system manufacturer locks down thermal tuning beyond what is usually done on the given platform. In that case user space calibration tools should not try to adjust the thermal configuration of the system. To allow user space to check if that is the case, add a new sysfs attribute "production_mode" that will be present when the ACPI DCFG method is present under the INT3400 device object in the ACPI Namespace.
