Argh, you're right, We've completely missed this.

And it's a *very* important point because we need this patch
to ultimately get rid of the mach/brideg-regs.h.

Quite frankly I'm really out of ideas right now and unless someone
comes up with a smart solution, I see no other way but to:

1. Implement an armada-wdt.c driver and stop trying to fix the world.
2. Add some ugly ifdefs to avoid the mach-specific header.
3. ?

In fact, I'm starting to think I should have started with (1) from the
beginning.
