[PATCH/RFC 04/14] arm64: dts: renesas: ironhide: Enable SCMI devpd, sys, and reset

SCP FW SDKv4.28.0 and later for Renesas R-Car X5H Ironhide not only
implements the SCMI base and clock management protocols, but also the
SCMI power domain, system power, and reset domain management protocols.

Enable support for the latter by adding the corresponding SCMI protocol
subnodes.
