ASoC: rsnd: setup clock-out only when all conditions are right

Browse source 
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.
