ASoC: rsnd: setup clock-out only when all conditions are right
Current adg.c doesn't assume that requested clock out divide condition doesn't match. In such case, it will indicate strange message, and will register NULL clock, etc. It is just a DT setting miss, but is confusable. This patch check all conditions for it.
