Yeah, Ivan objected to this, but incorrectly I think.

Ivan, your concern is about disabling things like interrupt controllers
and power management chips during probe right? You're right that doing
that could cause problems if we get and interrupt or PMU event at just
the wrong time, but that could just as easily happen if decode was
still enabled but the BAR had a bogus address programmed (as it would
during probing).

Ultimately, I don't care much one way or another as long as we can get
the desktop platforms fixed somehow. I think disabling decode is the
most correct way of doing this, but I'm open to other solutions (this
is the only patch I've seen though that's been tested to solve the
problem).
