Add new compatible string ti,am62-r5fss to support this scenario. When this new compatible is used cluster-mode property can only be set to value 3 i.e. CLUSTER_MODE_SINGLECORE which is also the default value in case cluster-mode is not defined in device-tree. While at it, also sort the compatible lists in alphabetical order.
