The loopback on the unused gpio inputs consumes routing resources
while does not gives any value for the software.
Connect these lines to zero instead.
- connect unused GPIO inputs to loopback
- connect unconnected inputs to zero
- complete interface for system_wrapper instantiated in all system_top
fixes incomplet portlist WARNING [Synth 8-350]
fixes undriven inputs WARNING [Synth 8-3295]
The change excludes the generated system.v and Xilinx files.
- remove interrupts from system_top
- for all suported carriers:
- remove all interrupt bd pins
- connect to GND all initial unconnected interrupt pins
- update ad_cpu_interrupt procedure to disconnect a interrupt from GND
before connectiong it to another pin.
This reduces the amount of boilerplate code that is present in these
Makefiles by a lot.
It also makes it possible to update the Makefile rules in future without
having to re-generate all the Makefiles.

Make sure that the axi_adxcvr instances are configured with the same
transceiver type as the util_adxcvr.
This is necessary for software to be able to detect the transceiver type
and support dynamic reconfiguration.
It is also necessary for correct eye scan support in the axi_adxcvr block.

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.

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:
