state[2].
In this patch,
When CPU exits state[2], it configures CCM to RUN mode.
When all CPUs enters state[2], the last CPU needs to check
whether it's ok to configure CCM to WAIT mode or not.

There is an OE(low active) input pin for 74hc595 and 74lv595.
To some boards, the OE pin is controlled by GPIO, so add an

Use devm_request_irq to simplify error handling path,
when probe smmu device.
Also devm_{request|free}_irq when init or destroy domain context.
