Added motion sense task to Clapper and Glimmer. This task samples the accelerometers and calculate a lid angle. Note that as the machine is rotated towards the hinge angle aligning with gravity, the lid calculation becomes less trustworthy. Added a math_util file to hold various mathematical functions useful for calculating lid angle that may be helpful in other places. For each board with accelerometers we need to define some orientation specific data in board.c. There is a calibration procedure through the EC console that can be enabled by defining CONFIG_ACCEL_CALIBRATE. The calibration procedure can help determine the orientation data required. For debugging purposes there is a console command to regularly print to the EC console the accelerometer data and derived lid angle. The console command can be enabled by defining CONFIG_CMD_LID_ANGLE. BUG=none Original-BUG=chrome-os-partner:24703 BRANCH=rambi TEST=Ran the calibration procedure on a Glimmer unit, and then rotated the machine in space. Verified that the lid angle calculated roughly matched actual lid angle.
