SSDT wouldn't get generated for an `off` device (non of the device ops
would be called). I guess the original _STA method is just redundant.
Specs says
```
If a device object describes a device that is not on an enumerable
bus and the device object does not have an _STA object, then OSPM
assumes that the device is present, enabled, shown in the UI, and
functioning.
```
