arm64: dts: renesas: r9a07g043: Create thermal zone to support IPA
Setup a thermal zone driven by SoC temperature sensor. Create passive trip points and bind them to CPUFreq cooling device that supports power extension. Based on the work done by Dien Pham <dien.pham.ry@renesas.com> and others for r8a77990 SoC.
