Remove PS related *_irqsafe functions to avoid entering/leaving PS under interrupt context. Instead, make PS decision in watch_dog. This could simplify the logic and make the code look clean. But it could have a little side-effect that if the driver is having heavy traffic before the every-2-second watch_dog detect the traffic and decide to leave PS, the thoughput will be lower. Once traffic is detected by watch_dog and left PS state, the throughput will resume to the peak the hardware ought to have again.
