void __init adapter_init_scsi_host (struct Scsi_Host * host);
values that we have already stored in the adapter instance. There's some mention that a lot of these are deprecated, so we won't use them (we'll use the ones in the adapter instance) but we'll fill them in in case something else needs them.
The eeprom structure, irq and io ports in the adapter need to have been set before calling this function.
