Install the callbacks via the state machine so we can phase out the cpu
hotplug notifiers..

Didn't Sebastian come up with a version of the hotplug state callbacks
that can be per-object?  This seems to be a perfect candidate for that.

Indeed. I wrote that myself and forgot about it already..... :(

So yes, we can use that and get rid of blk-mq-cpu.c completely.

Thanks,
