HID: sensor-hub: add sensor hub quirk for ThinkPad Helix
Just like some of the other laptops/tablets on the market with ultrabook sensors, the ThinkPad Helix's sensor hub requires a special quirk in order for it to power on properly. Without it the sensors are detected by the kernel and set up as usual, but they won't output any data. This will also fix the sensors on any other laptops with the same model of sensor hub.
