[PATCH] iio: magnetometer: si7210: fix magnetic field measurement scale

[Antoni Pokusinski <apokusinski01@gmail.com>]

Applying the current scale value to the raw magnetic field measurements
gives the result in mT.

Fix the scale by increasing it 10 times, so that the final result after
applying the scale is in Gauss.
