atari_scsi: Convert to platform device
Convert atari_scsi to platform device and eliminate scsi_register(). Validate __setup options later on so that module options are checked as well. Remove the comment about the scsi mid-layer disabling the host irq as it is no longer true (AFAICT). Also remove the obsolete slow interrupt stuff (IRQ_TYPE_SLOW == 0 anyway).
