drm/amd/display: Block zstate when more than one plane enabled
[Why] Currently Z10 save/restore only covers 1 plane case. If we enter Z10 with 2 planes enabled, 1 of the 2 planes will not be restored. causing black screen. [How] Disable Zstate when more than 1 plane is enabled. Right now Z9 enable but Z10 disable is not a supported config, so we disable both.
