dt-bindings: remoteproc: ti: Add new compatible for AM62 SoC family 



AM62 family of devices don't have a R5F cluster, instead they have
single core DM R5F.  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.
