motion_sense: Add CONFIG_DYNAMIC_MOTION_SENSOR_COUNT config option
Some projects, such as Coral use a common image to support different
SKUs. In this case the number of motion sensors supported may need to
be determined at runtime. CONFIG_DYNAMIC_MOTION_SENSOR_COUNT removes
the const assumption for the global variable motion_sensor_count.
