[PATCH RFC 1/3] arm64: dts: qcom: nord: Add SoCCP remoteproc DT support for Nord

[Anurag Pateriya]

Add the SoCCP (System on Chip Control Processor) remoteproc node and
its SMP2P configuration at the SoC level in nord.dtsi, and wire up
the clock and power-domain dependencies shared by all Nord embedded
variants in nord-embedded.dtsi.
