Some devices, including most Microsoft Surface devices, have a platform
profile somewhere inbetween balanced and performance. More specifically,
adding this profile allows the following mapping on Surface devices:
Vendor Name Platform Profile
------------------------------------------
Battery Saver low-power
Recommended balanced
Better Performance balanced-performance
Best Performance performance
