[RFC PATCH 0/8] PM / Domains: Add support for removing PM domains

[jonathanh@nvidia.com (Jon Hunter)]

In order to safely remove PM domains there are a few changes that need to be
made to ensure that no one is holding an external reference to a PM domain
after it has been removed. One solution, implemented here, solves this by
eliminating external references to PM domain. Another alternative would be
to employ some reference counting for the PM domains, however, I did not see
a good reason for allowing external references in the first place (as always
there could be something that I have over-looked!).
