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
