Make measurements right-justified, since it is the default for the
driver and sensor. By not setting the ADXL345_DATA_FORMAT_JUSTIFY bit,
the data becomes right-judstified. This was the original setting, there
is no reason to change it to left-justified, where right-justified
simplifies working on the registers.
