[PATCH 00/10] 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.

This is a follow-up to the initial RFC I sent out [0].

Changes from initial RFC:
- Renamed functions made static per Ulf's feedback.
- Added patch to clean-up provider/xlate APIs per Ulf's feedback
- Re-worked and simplified the association between PM domains and PM
  domain providers. Dropped the 'provider_data' variable from the
  generic_pm_domain structure in favour of using the fwnode_handle.
- Split patch for removing PM domains into multiple patches per Ulf's
  feedback.
