Unfortunately, still too much exposure of port-config to drivers for
my liking.  I'd be happier with an API that requests the mode for a
specific pin group instead of directly masking & setting bits....

but of course I've also just said in my other email that I'd be happy
with all of the GPIO AC97reset logic being contained in
arch/powerpc/platforms/52xx which kind of makes the comment moot.  :-)
