description:
Program the 53c96's interrupt routing info into the VIA before doing
anything that might cause an interrupt (e.g. the SCSI bus reset in
ncr53c9x_attach()).  If we don't do this, the initial interrupt is
lost, thus causing the state machine to never enter IDLE state, thus
causing SCSI commands to never be executed.

Fixes kern/8544, reported by Erik Bertelsen <erik%mediator.uni-c.dk@localhost>.
