[Why] The current implementation for idle optimization support only has a single work item that gets reshuffled into the system workqueue whenever we receive an enable or disable event. We can have mismatched events if the work hasn't been processed or if we're getting control events from multiple displays at once. This fixes this issue and also makes the implementation usable for PSR control - which will be addressed in another patch. [How] We need to be able to flush remaining work out on demand for driver stop and psr disable so create a driver specific workqueue instead of using the system one. The workqueue will be single threaded to guarantee the ordering of enable/disable events. Refactor the queue to allocate the control work and deallocate it after processing it. Pass the acrtc directly to make it easier to handle psr enable/disable in a later patch. Rename things to indicate that it's not just MALL specific.
