The DRM pipeline, as it runs in automatic restart mode, never sees the
pipeline state set to VSP1_PIPELINE_STOPPING or VSP1_PIPELINE_STOPPED
when running the frame end interrupt handler. We can thus skip the
checks various checks in the handler and return immediately.
Similarly the DRM frame end handler calls vsp1_pipeline_run()
unnecessarily, as the state there is never VSP1_PIPELINE_STOPPED. Remove
the function call and the frame end handler is it's now empty.
