Sensitivity Percent Relative is added for ambient light sensor as it is used based on HID Sensor Usages specifications.
Other changes include adding HID_USAGE_SENSOR_LIGHT_ILLUM and HID_USAGE_SENSOR_ATMOSPHERIC_PRESSURE for ambient light and pressure sensor respectively to be in sync with HID Sensor Usages specifications.
