The smmu needs to be functional only when the respective
master's using it are active. The device_link feature
helps to track such functional dependencies, so that the
iommu gets powered when the master device enables itself
using pm_runtime. So by adapting the smmu driver for
runtime pm, above said dependency can be addressed.

This patch adds the pm runtime/sleep callbacks to the
driver and also the functions to parse the smmu clocks
from DT and enable them in resume/suspend.

General comment, we have a bulk clk API now, but I guess we
failed to add the clk_bulk_prepare_enable() API that could be
used here. Perhaps you can add that API and then use it here to
reduce lines of code.

Bjorn just sent a patch for that API an hour ago.
