Istvan Csomortani 9055774795 all: Update license for all hdl source files
All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.

New license looks as follows:

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.
