instead of having every bit of glue set up and attach an identical
scsi_adapter struct, just do it once in the chip code.

Do not use NULL in integer comparisons. No functional change.

Remove all adapter-specific 'struct scsi_device's. They are never used. First

Yup, I managed to fat finger all three of these while doing bus_dmamap_sync()
conversion (luckily only sparc64 uses the 5 arg form so far =)

deal with 5 arg for of bus_dmamap_sync() if available

Change pci_intr_map to take pci_attach_args as an argument.
All callers actually took all arguments to pci_intr_map from pci_attach_args
structs, so this simplifies code.
This also allows more complicated interrupt assignment schemes like the one
on sparc64.

This makes sparc64 pci interrupts work.

Inspired by the same change in NetBSD.

Make pci_mapreg_map take an extra argument where we can
put a size limitation of the PCI region to map. That makes the PERC 3/Di
raid controller usable, as it publishes too much PCI memory for us to map
in the kernel virtual memory. As we only access the first 256 byte it is
of no use to map 128MB of kvm.
