driver: lsm6ds0: Add bias offset code
Add code to store bias from AP at boot and correct
raw data from accelerometer on the fly.
Also return the raw data on 16 bits, as recommned by sysfs.
BRANCH=smaug
BUG=chromium:506101
TEST=check set and get offset works fine.
Check value from accelerometer are sane (on Samus).
