Finn Thain f877958879 NuBus header update 
Sync the nubus defines with the latest code in the mac68k repo. Some of these
are needed for DP8390 driver update in the next patch.

nubus.h: various definitions and prototypes for NuBus drivers to use.
Originally written by Alan Cox.
Hacked to death by C. Scott Ananian and David Huggins-Daines.
Some of the constants in here are from the corresponding
NetBSD/OpenBSD header file, by Allen Briggs. We figured out the
rest of them on our own. */
