In this specific case, the above is related to one of the sequencers being stuck, while client drivers are returning from probe and trying to disable the currently unused clock and interconnect resources. Generally we want to keep the multimedia NoC enabled like the rest of the NoCs, so let's set the keepalive flag on it too.
