  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 don't allow cluster-mode
property usage in device-tree as this implies that there
is no R5F cluster available and only single R5F core
is present.

The DT people need to ack this patch, and for that to happen they need to be
CC'ed on the patch, as checkpatch is explicitly instructing to do.
