iio: humditiy: hdc3020: fix units for temperature and humidity measurement
According to the ABI the units after application of scale and offset are
milli degrees for temperature measurements and milli percent for relative
humidity measurements. Currently the resulting units are degree celsius for
temperature measurements and percent for relative humidity measurements.
Change scale factor to fix this issue.
