[ Upstream commit c337125b8834f9719dfda0e40b25eaa266f1b8cf ]
We can get "failed to disable" clock_unprepare warnings on unbind at least for the serial console device if the unbind is done before the device has been idled.
As some devices are using deferred idle, we must check the status for pending idle work to idle the device.
