Add cfg files for Hitex LPC1768 Stick
Website: http://www.hitex.com/?id=1602



This board has a FTDI2232D as JTAG interface, using the
same layout as the Hitex STM32-PerformanceStick but with
different USB PID.

Main MCU is a LPC1768 from NXP.

The interface config uses the ftdi driver instead of ft2232.
The corresponding ft2232 layout would be "stm32stick".
