Also the power domain driver could manage the clocks as well, I would
suggest to use pm_runtime_*.
actually the clocks required by pm domain may not be the same as what we
want to control here, there might be some clocks only be needed when
accessing mmu registers.
but i'm not very sure about that, will confirm it with Simon Xue.
confirmed with Simon, there might be some iommus don't have a pd, and
the CONFIG_PM could be disabled.
so it might be better to control clocks in iommu driver itself.
