platform/x86: asus-wmi: export symbols used for read/write WMI

Browse Source 
Export symbols for reading/writing WMI symbols using a namespace.
Existing functions:
- asus_wmi_evaluate_method
- asus_wmi_set_devstate
New function:
- asus_wmi_get_devstate_dsts

The new function is intended for use with DSTS WMI method only and
avoids requiring the asus_wmi driver data to select the WMI method.
