[SCSI] advansys, arcmsr, ipr, nsp32, qla1280, stex: use pci_ioremap_bar()

Use the newly introduced pci_ioremap_bar() function in drivers/scsi.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.
