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.
