arm64: dts: juno: Add separate SCMI variants
While Juno's SCP firmware initially spoke the SCPI protocol, binary
releases since 2018, and the newer open-source codebase, only speak SCMI
and thus aren't particularly compatibile with the DTs we currently have
upstream. Add a parallel set of variant DTs for boards with up-to-date
firmware, replacing the SCPI parts with their new SCMI equivalents.
