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.
Changes from V1:
- Added test when removing a PM domain to ensure the PM domain provider
has been removed.
- Re-organised patches 8-10 so that patch #8 adds the code to verify if
the provider is present, patch #9 adds basic support for removing PM
domains and patch #10 adds support for removing PM domains by provider.
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.
