iio: light: opt3001: add missing full-scale range value

The opt3001 driver uses predetermined full-scale range values to
determine what exponent to use for event trigger threshold values.
The problem is that one of the values specified in the datasheet is
missing from the implementation. This causes larger values to be
scaled down to an incorrect exponent, effectively reducing the
maximum settable threshold value by a factor of 2.

Add missing full-scale range array value.
