Small adjustment the scale calibration value for the sc2731,
use new name sc2731_[big|small]_scale_graph_calib, and remove
the origin [big|small]_scale_graph_calib struct for unused.

Fixes: 8ba0dbfd07a35 (iio: adc: sc27xx: Add ADC scale calibration)

Why Add?

Given the variable naming conveys this anyway, I would drop the comment entirely.

I dropped the comment whilst applying and added sc27xx to the patch title prefix.
