rammus: Correct accel sensor BMI160 base reference dependent on sensor location.
Base on BMI160 location, the x axis is positive correlation
and the y, z axis negative correlation.
Correct the MB base reference direction.
BUG=b:118362153
BRANCH=ToT
TEST=Manual
1. Using EC console command "accelinfo on" the check the
