Having a clock assigned manually to the clk output pin of the axi_ad9361
let the Vivado timing engine to not ignore the clock insertion delay when
analyzing paths between clk_0 and the manually created clock that has
the same source (clk_0), resulting in timing failure.
Use the new util_cpack2 and util_upack2 cores. They have lower utilization
that the old util_cpack and util_upack cores.

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.
- 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.
In the system top of the FMCOMMS5 projects, there are several GPIO lines, which
can not find in the constraint file, respectively gpio_open_15_15,
gpio_open_44_44 and gpio_45_45.
These are floating GPIO pins, as their names suggest. Delete all these wires and
update IOBUF instances.
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.

Loop back the unused GPIO pins, and add all the SPI interface to system
wrapper instance.
The following system_top modules were changed:
- ad738x_fmc
- ad7616_sdz
- ad77681evb
- ad77681evb
- ad7768evb
- ad9739a_fmc
- ad9434
- adrv9739
- fmcadc5
- ad6676evb
- ad9265
- ad5766
- fmcomms5
- m2k
Fixes the following warnings:
[Synth 8-2611] redeclaration of ansi port txnrx_0 is not allowed
[Synth 8-2611] redeclaration of ansi port enable_0 is not allowed
[Synth 8-2611] redeclaration of ansi port enable_1 is not allowed
[Synth 8-2611] redeclaration of ansi port txnrx_1 is not allowed
This is a leftover of commit 1c23cf4621 ("all: Update verilog files to
verilog-2001").

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:

- for altera projects, taken into consideration of the new location for common qsys files
- for fmcomms5, added wfifo dependency
- for daq3, added mfifo dependency
Re-generate the Makefiles after a small update to the generation script:
- Entries are sorted alphabetically
- Empty dependency lines are skipped
