lis3lv02d: fix some comments specific to lis331dlh driver 

Fix some minor problems in comments of lis331dlh driver
  * correct comments with respect to 2G sensitivity
  * correct typo lis3331dlh mistake to lis331dlh
  * add comment to say only 2G range is supported
  * change the function name from lis3lv02d_read_16 to
    lis331dlh_read_data.
  * update i2c_device_id table entry to maintaine consistancy
  * update sensor display message
