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.
