Matt Jacob 9b63136347 Add support for the LSI-Logic Fusion/MP architecture. 
This is an architecture that present a thing message passing interface
to the OS. You can query as to how many ports and what kind are attached
and enable them and so on.

A less grand view is that this is just another way to package SCSI (SPI or
FC) and FC-IP into a one-driver interface set.

This driver support the following hardware:

LSI FC909:	Single channel, 1Gbps, Fibre Channel (FC-SCSI only)
LSI FC929:	Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only)
LSI 53c1020:	Single Channel, Ultra4 (320M) (Untested)
LSI 53c1030:	Dual Channel, Ultra4 (320M)

Currently it's in fair shape, but expect a lot of changes over the
next few weeks as it stabilizes.

Credits:

The driver is mostly from some folks from Jeff Roberson's company- I've
been slowly migrating it to broader support that I it came to me as.

The hardware used in developing support came from:

	FC909: LSI-Logic, Advansys (now Connetix)
	FC929: LSI-Logic
	53c1030: Antares Microsystems (they make a very fine board!)

MFC after:	3 weeks
