I added the _noirq part to the names of the callbacks, since otherwise the
second struct looks confusingly similar to the first one.

I also could have put the _noirq callbacks into the first struct, but that
would have been wasteful, since device types and device classes don't
use them.  Also, the majority of bus types won't use them and the vast majority
of drivers won't use them as well.

Thanks,
