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:

The axi_adc_decimate does not use the full width of the AXI interface
address. It only responds to register access in the first 32 registers.
Reduce the size of the AXI address to 7 bit accordingly. This allows the
scripts to correctly infer the internal register map size which will cause
the interconnect to filter out access to these unused register.
This slightly reduces utilization by getting rid of some pipeline
registers.

Move the processing pipeline of the axi_adc_decimate core to its own
sub-module. This makes it easier to simulate the processing independent of
the register map.
