iio: light: apds9306: fix max_scale_nano values
commit a96d3e2beca0e51c8444d0a3b6b3ec484c4c5a8f upstream.
The two provided max_scale_nano values must be multiplied by 100 and 10
respectively to achieve nano units. According to the comments:
Max scale for apds0306 is 16.326432 → the fractional part is 0.326432,
which is 326432000 in NANO. The current value is 3264320.
Max scale for apds0306-065 is 14.09721 → the fractional part is 0.09712,
which is 97120000 in NANO. The current value is 9712000.
Update max_scale_nano initialization to use the right NANO fractional
parts.
