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:

Can not be multiple 'if' statements inside a generate block. If there are
multiple cases use if/esle statement, but always should be one single
if/else inside a generate.
Currently the IDDRs are configured in SAME_EDGE_PIPELINED mode, but then
the negative data is delayed by an additional clock cycle. This is the same
behaviour as using the IDDR in SAME_EDGE mode.
Switching to SAME_EDGE mode removes extra pipelining registers while
maintaining the same behaviour.

In modules ad_serdes_in/ad_serdes_out the handover of the parameter
SERDES_FACTOR did not exist, causing unwanted behavioral in case of
factors less than 8.
SERDES_FACTOR must be hand over to DATA_WIDTH parameter of the SERDES
primitive.
