Fix support for PS/2 keyboard on TQM85xx boards
The PS/2 keyobard driver for the TQM85xx modules only supports the internal DUART of the MPC85xx CPU. Since the MPC8560 doesn't include a DUART, the TQM8560 modules can't be used with the PS/2 keyboard controller on the STK85xx board. The PS/2 keyboard driver should work with the modules TQM8540, TQM8541 and TQM8555, but it only has been tested on a TQM8540, yet. Make sure the PS/2 controller on the STK85xx is programmed. Jumper settings: X66 1-2, 9-10; X61 2-3 Patch by Martin Krause, 21 Jun 2006
