thorpej d6f4511690 All interrupt routines (except the HIL; don't ask) now take a pointer
to a softc, rather than a unit number.  Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.

YAY!  No more need for dcafastservice!

HIL: squish instances of "(void) splhil()" and "(void) spl0();".
