tcl: Add support for the Numato Lab Mimas A7 board

The Mimas A7 FPGA board has FTDI FT2232 whose channel B is connected to
Artix-7 FPGA's JTAG interface. Hence, OpenOCD can easily interface with
it via the its ftdi driver interface. Tested to be working great up to
30 MHz.

# Note: Connect external DC power supply if programming a heavy design onto FPGA.
# Programming while powering via USB may lead to programming failure.
# Therefore, prefer external power supply.
