Alec Berg 2356c3e213 rambi: Rotate accelerometer data into standard reference frame ...

Added rotation of accelerometer data into a standard reference frame
so that the host does not have to know about the orientation of the
sensors.

Also added a calibration routine to calibrate the rotation matrix to
get to the standard reference frame. Cleanup up calibration in the
process to make it more user friendly.

Changed the default accelerometer sampling rate to 100Hz.

BUG=chrome-os-partner:25599
BRANCH=rambi
TEST=Tested the full calibration routine on a glimmer at my desk.
Used 'taskinfo' and verified that the higher sampling rate does not
bog down the EC. I found that the motion sense task is running for
about 200ms every 10 seconds, so about 2% CPU load.
