iio: sc27xx_adc: Use DIV_ROUND_CLOSEST() instead of open-coding it
Use DIV_ROUND_CLOSEST() instead of open-coding it. This makes it more clear
what is going on for the casual reviewer.
Generated using the following the Coccinelle semantic patch.
// <smpl>

expression x, y;
@@
-((x) + ((y) / 2)) / (y)
+DIV_ROUND_CLOSEST(x, y)
