Added usage id processing for Proximity (Human Presence). 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.

Add a new driver for the ambient light/proximity sensor device. The driver exposes three channels: light_clear light_ir and proximity. It also supports triggered buffer, high and low ambient light threshold event and proximity detection events.
