From: Kieran Bingham <kieran.bingham+renesas@xxxxxxxxxxxxxxxx>
The suspend and resume handlers are only utilised by video pipelines,
yet the functions currently reside in the vsp1_pipe object.
This causes an issue with resume, as the functions incorrectly call
vsp1_pipeline_run() directly instead of processing the video object
through vsp1_video_pipeline_run().
Move the functions to the video object, renaming accordingly and update
the resume handler to call vsp1_video_pipeline_run() as appropriate.
