ASoC: topology: Remove unnecessary looping
Functions creating kcontrols as written allow for creation of multiple kcontrols at the same time, but in practice they are called for each kcontrol individually. Remove unnecessary loop as code always loops once anyway. This reduces intendation level allowing for some code to be put on one line instead of multiple lines.
