Subject: [PATCH V4 3/7] iio: adc: Fine tune the scale calibration values

From: Cixi Geng <cixi.geng1@...soc.com>

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)
