I guess nobody has tried building a CATS kernel for a couple of weeks.

One or other of sys/arch/arm/include/isa_machdep.h and
sys/arch/arm32/isa/isa_cats_machdep.c are incorrect.

The first argument to isa_fillw() has been changed from u_short to u_int
for the prototype but not for the implementation.

I can't find anything that uses isa_fillw() so maybe it should just
be deleted.
