From: Alvin Lee <alvin.lee2@xxxxxxx> [Description] For no plane scenarios we should not consider cursor as there cannot be any cursor if there's no planes. This fixes an issue where dc_commit_streams fails due to prefetch bandwidth requirements (the display config + dummy planes + cursor causes the prefetch bandwidth to exceed what is possible).
