AM62 SoC family don't have a R5F cluster, instead they have a single
core R5F. This enables IPC support with single core R5F for AM62
family of SoCs.

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.

2.17.1
AM62 and AM62A SoCs use single core R5F which is a new scenario
different than the one being used with CLUSTER_MODE_SINGLECPU
which is for utilizing a single core from a set of cores available
in R5F cluster present in the SoC.
To support this single core scenario map it with
newly defined CLUSTER_MODE_NONE and use it when
compatible is set to ti,am62-r5fss.

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.
