This commit adds the base accelerometer as well as the gyroscope to the list of motion sensors on the board. They are currently wrapped behind an ifdef for HAS_TASK_MOTIONSENSE due to space constraints. BUG=chrome-os-partner:43494 BRANCH=None TEST=Build GLaDOS EC with driver enabled and verify that we can calcuate a valid lid angle. TEST=Verify that signs of accelerometer conform to those shown in the Chrome/Android/HTML5 doc/spec. See description in accelerometer_types.h TEST=Verify that signs of gyroscope conform to those shown in the "Sysfs interface to EC accelerometers" document.
