driver: bmi160: use rotation matrix to handle offsets.
Store offsets using sensors axis, not the device axis.
Therefore apply rot_standard_ref to the offset vector before
get and rot_standard_ref^-1 before set.
BRANCH=smaug
TEST=using mag sensor, check the offset are applied to the right axis
and store correctly.
BUG=chromium:517675
