Hi folks...

I've just committed a round of changes to the SCSI code, which clean up
a few things, in preparation for some other work I'll be doing there.  The
changes should not affect you, tho you will notice that detection of SCSI
devices is deferred until a little later in the autoconfiguration cycle:

bha0 at pci0 dev 12 function 0: BusLogic 9xxC SCSI
bha0: interrupting at irq 11
bha0: model BT-958, firmware 5.05R

scsibus0 at bha0: 16 targets, 8 luns per target

The changes are written such that if I missed updating a driver, it won't
compile.  If you encounter any of this, please send a PR, and I'll address
it as quickly as possible.

Thanks!
