iio: st_sensors: Add lsm303d support to the LSM9DS0 IMU driver

The lsm303d is basically the lsm9ds0 without the gyroscope
(which the LSM9DS0 IMU driver doesn't handle), as far as I
can tell.

          To compile this driver as a module, choose M here: the module
          will be called st_lsm9ds0.
