driver: bmi160 Add code for calibration
Add code for set/getting calibration data on bmi160
Add code to perform FOC (Fast Online Calibration) on bmi160.
Add delay after getting out of suspend to be sure sensor is
available.
BRANCH=smaug
TEST=Check sensors are properly calibrated on Smaug:
Perform calibration:
echo 1 > /sys/bus/iio/devices/iio:device1/calibrate
Read calibration values:
cat /sys/bus/iio/devices/iio:device1/*_calibbias
Check the values are translated properly.
Write calibration values and check it affects the
sensor output.
