[PATCH 4.9 19/44] iio/gyro/bmg160: Use millidegrees for temperature scale

From: Mike Looijmans <mike.looijmans@topic.nl>

commit 40a7198a4a01037003c7ca714f0d048a61e729ac upstream.

Standard unit for temperature is millidegrees Celcius, whereas this driver
was reporting in degrees. Fix the scale factor in the driver.
