Lars-Peter Clausen 17dff9ce90 util_cic: Allow partial gating of CIC comb and int stages
Allow to split a CIC int or comb block into multiple stages and be able to
dynamically gate some of the stages. Also prevent carry propagation in
gated stages to keep the adder output constant.

This is useful for multi-rate filter where not all bits are needed all the
time.
