Given that AMBA gets the runtime PM status across a probe, none of this
should be necessary, as generic PM domains ensures that if runtime PM
is active for any device bound to the PM domain, the PM domain will be
powered up.

In that respect, AMBA is a model of how runtime PM should've been done
for stuff like platform devices. :)
