New toner supply motor control circuit

The new toner supply motor, which is a DC motor driven by control signals from the main-CPU on the
LGC board, rotates the toner cartridge.
This motor is driven when the on/off signal (TNRMTON-0) output from the main-CPU moves to a high
level. The motor rotation direction switching signal (TNRMTCW-0) switches the rotational direction of
this motor.
