I do not expect caches in the same power domain to have different retention
capabilities, so a flag per-state should be enough. If anyone is unhappy
about this please flag it up. List of caches affected can be retrieved by
walking the power-domain specifiers and check those against the caches power
domains.
Thanks,
Lorenzo
