Major rework to support Qlogic ISP2100 (Fibre Channel PCI card). Also now

able to read SXP registers (instead of panicing). Probably have done a bit
of setup overkill- we now alloc some scratch memory for the 2100 that I thought
I would need for the Port database, but so far I haven't needed to retrieve
the port database. Well, early days yet.
