Add the pins used by the LCD controller, the panel-info and display-timings information for the MIDAS displays connected to the board. There are two displays in the board, and these, are connected to the LCD controller through a FPGA, so the timings and the resolution is what expects the FPGA, not the MIDAS displays.
