Srinivas Pandruvada	56ff6be608	iio: hid-sensors: Add API to power on/off ... Added an API to allow client drivers to turn ON and OFF sensors for quick read. Added data_read as counting varaible instead of boolean, so that sensor is powered off only when last user released it.

Srinivas Pandruvada	fc18dddc06	iio: hid-sensors: Added device rotation support ... Added usage id processing for device rotation. This uses IIO interfaces for triggered buffer to present data to user mode.This uses HID sensor framework for registering callback events from the sensor hub. Data is exported to user space in the form of quaternion rotation format.
