drm/amd/display: Don't consider cursor for no plane case in DML1

Browse Source 
[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).
