iio: adc: sc27xx: Fine tune the scale calibration values

Browse Source 
[ Upstream commit 5a7a184b11c6910f47600ff5cbbee34168f701a8 ]

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.
