The *_runtime_suspend/resume() callbacks perform basic operations
necessary before/after turning off/on clocks using *_runtime_put/get*().
This happens when modules are fully initialized and functional.
They don't have to be called during initialization. As we need the clocks
to be turned on/off using *_runtime_get/put*() in *_probe() make sure
we return from these callbacks during this time.
