This patch is preparatory for adding the Bosh BNO055 IMU driver. The said IMU can report raw accelerations (among x, y and z axis) as well as the so called "linear accelerations" (again, among x, y and z axis) which is basically the acceleration after subtracting gravity. This patch adds IIO_MOD_ACCEL_LINEAR_X, IIO_MOD_ACCEL_LINEAR_Y and IIO_MOD_ACCEL_LINEAR_Z modifiers to te IIO core.
