iio: hid: Add humidity sensor support
Environmental humidity sensor is a hid defined sensor,
it shows raw humidity measurement of air.
More information can be found in:
http://www.usb.org/developers/hidpage/HUTRR39b.pdf
According to IIO ABI definition, humidityrelative data output unit is
milli percent. Add the unit convert from percent to milli percent.
