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.
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.

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:

The ADV7511 samples the parallel data bus at the rising edge of sample
clock. Generate the clock so that the falling edge is aligned to updating
the bus data. This creates larger timing margins on each side of the
sampling edge and makes the design more robust.

Increase the RX DMA FIFO to be able to better compensate for momentarily
memory bus contention. This has shown to resolve occasional overflows that
would occur under high system memory load.

Connect the HDMI RX core output clock to the DMA rather than connecting the
HDMI RX input clock directly. This will allow the HDMI RX core to modify
the clock and e.g. insert clock buffers or similar.

The ADV7611 is rated for a maximum clock rate of 165MHz. Increase the clock rate constraint to match this.

The axi_dmac core is now capable of detecting whether its different parts
run in different clock domains or not. No need to configure it manually any
more.
