Add an interface file for DLP Design DLP-USB1232H.

The DLP Design DLP-USB1232H UART/SPI/JTAG module is based on an FTDI FT2232H
chip. Among other things, it can used as JTAG programmer if connected to
the JTAG target properly. I have successfully wired the module to an
Olimex STM32-H103 eval board and flashed a firmware onto that using OpenOCD.

The setup details and schematics are documented at:
