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
