Use the new util_cpack2 and util_upack2 cores. They have lower utilization
that the old util_cpack and util_upack cores.

- 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.
Removes a lot of boilerplate code.
Using the new scheme it is possible to add new projects or sub-projects
without having to re-generate any existing Makefiles.

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
The constraint where added to remove timing problems on the reset path.
The constraint paths do not match anymore. The resets are used in a synchronous
way so we don't need the timing exceptions anyway.
Projects affected by this change:
- daq3
- adrv9739
- ad6676evb
- fmcadc5
- daq2/kcu105
- fmcadc2
- adrv9371x
- fmcomms11/zc706
- fmcjesdadc1
The script specifies the OUT_CLK_SEL and SYS_CLK_SEL parameter values as
binary numbers. But the tools will interpret them as decimal number
resulting in the wrong selection for OUT_CLK_SEL. Specify the parameter
values as decimal values to avoid this.
This is not a critical issue since software will overwrite this setting at
system boot-up. But it should be fixed anyway.

Convert the AD6676EVB project to the ADI JESD204 link layer core. 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:

If a parameter value is defined as a string binary (e.g. "001001000000"),
it can confuse the tool, and the value may be used as a decimal number.
To prevent this issue and to improve readability converting all the binary
constants into hexadecimal.
Xilinx recommends that all synchronizer flip-flops have
their ASYNC_REG property set to true in order to preserve the
synchronizer cells through any logic optimization during synthesis
and implementation.
