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.
