dt-bindings: firmware: arm,scmi: Allow multiple instances

Enable multiple SCMI instances by appending an instance-number suffix
to the 'scmi' node name. The SCMI spec assumes a single SCMI platform,
but in practice its responsibilities may be split across several SCMI
platform/server instances. However, only one instance can serve as the
system-wide (true) SCMI platform.
