React to link management on powered pipelines by updating the use count of
all entities in the source and sink sides of the link. Entities are powered
on or off accordingly. The use of this function should be paired
with v4l2_pipeline_pm_use.
Return 0 on success or a negative error code on failure. Powering entities off is assumed to never fail. This function will not fail for disconnection events.
