tcl: Add support for the Digilent Nexys Video board 

* https://store.digilentinc.com/nexys-video-artix-7-fpga-trainer-board-for-multimedia-applications/
* https://reference.digilentinc.com/_media/nexys-video:nexys_video_sch.pdf

The Nexys Video board has FTDI FT2232 whose channel B is connected to
Artix-7 FPGA's JTAG pins, and can be supported by OpenOCD's
ftdi interface. Tested to be working fine on real hardware.
