From: Hari Kanigeri <h-kanigeri2@xxxxxx>
Removed resource cleanup for DMM on PROC_Detach due to LCML
detaching the processor when it deletes each node, therefore
resource cleanup was freeing DMM resources of other nodes that
might be still in use, this would cause unexpected behavior,
possibly MMU fault.
