If the controller isn't clocked or its domain powered up, the register
accesses will either stall the CPU or return garbage, respectively.
Thus, we had a warning in our register access function to complain when
that kind of risky accesses were performed.
In order to check the runtime_pm power state, we were using
pm_runtime_active(), but it turns out that it will become active only
once the runtime_resume hook has been executed.
This prevents us from doing any WARN-free register access in our
runtime_resume() implementation, while this is valid.
Let's switch to pm_runtime_status_suspended() instead.
