Implement storage driver for QLogic ISP SCSI chips

These SCSI controllers were rare on PCs but common on DEC Alpha systems. This driver is required for the ROS VW port. QLogic never released technical manuals for their ISP chips, some details about the hardware can be found by looking up the Linux and BSD drivers:

QLogic emulation is implemented in 86Box:
