At least until virtualization of plane hw is done. So makes sense to outright disable all the slave plane stuff for now. And I think it's ok to keep all the code still, we'll use it again.

Since even with this change, that still can not pass all our tests. we have to update the user tests or the komeda implementation. Once we finished the updating, we still need to revert this change. So maybe just drop it is more better.

Since the property slave_planes have been removed, to avoid the resource assignment problem in user disable slave pipeline support temporarily.
