Instead of adding those calls to each driver, we can be smart and flag the
interrupt as AUTO_RUNTIME_SUSPEND or such.
So the runtime_pm core can handle it when invoking the
dev_pm_ops->runtime_suspend()/resume() callbacks.
Unfortunately the devres stuff is exceptionally bad to be used for this, but
with some surgery it should be doable.
Thanks,
