Use the sys_dma_clk clock module for clock and reset signals of the data
path, rather than using the A10GX specific sys_ddr3_cntrl signals. This
enables compatibility for all Altera/Intel platforms.

Provide the correct lane mapping for the DAQ2 DAC lanes which do not follow
a 1-to-1 mapping between physical and logical lanes due to PCB layout
constraints.

Convert the DAQ2 project to the ADI JESD204 link layer cores. The change is
very straight forward, but a matching change on the software side is
required.

Move the CDC helper modules to a dedicated helper modules. This makes it
possible to reference them without having to use file paths that go outside
of the referencing project's directory.

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:

Currently the DAC FIFO size for the ZC706 DAQ2 project is 16kB. This is
quite a limiting size for practical applications. Increase the size to 1MB
to allow loading larger waveforms.
In this configuration the DAC FIFO will use half of the available BRAM
cells in the FPGA. This still leaves quite a few BRAMs available for
user application logic added to the design. If a user design should run out
of BRAMs nevertheless they can reduce the FIFO size, if not required by the
application, to free up some cells.
