Gwendal Grignou de42bb285f motion_sense: calculate threshold properly ...

Working on light sensor, sensor were read on every time,
SENSOR_EC_THRES was not taken into account.
Fix 64/32 conversions and add a function for dealing with rollover.

TEST=Set light sensor probe at 1s. Set accel sensor at 100Hz to fill
fifo often; verify that light sensor is queried every second only.
