iio: hid: Add temperature sensor support
Environmental temperature sensor is a hid defined sensor, it measures temperature. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR39b.pdf According to IIO ABI definition, IIO_TEMP data output unit is milli degrees Celsius. Add the unit convert from degree to milli degree.
