description:
Add a bus.h blanket header which forces definition of bus space /
bus dma interfaces as functions and therefore makes it possible to
use rump on archs which suffer from macro maladies, i.e. everything
except i386 and amd64.

(build-tested on sparc64 and vax, which are usually the two extremes
of weirdness in these cases)
