This commit adds support for ADALM-PHASER, allowing the user to choose between the default PlutoSDR mode and Phaser mode
through a software controlled GPIO pin: phaser_enable.
The Generic TDD Engine was integrated to output a logic signal on the L10P pin, which connects to the input of the ADF4159,
when receiving an external synchronization signal on the L12N pin from the Raspberry Pi. Two additional TDD channels are used
to synchronize the TX/RX DMA transfer start:
- TDD CH1 is connected to the RX DMA, triggering the synchronization flag;
- TDD CH2 is connected to the TX unpacker's reset, backpressuring the TX DMA until deasserted.

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.
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.
