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.

The same patch is submitted by Song Hongyan <hongyan.song@intel.com>
. We may need new IIO ABI to specify relative percent hyst.

Thanks,
Srinivas

It is a particularly 'hideous' way of reporting something - particularly
as we head towards very low values.  Ah well. Yes, would need
some additional ABI.  We do already have ratio attributes so
maybe - 
hysteresis_ratio or something like that.   Ugly though.  Ah well.
