Subject: [PATCH v2 4/9] dt-bindings: thermal: r9a09g047-tsu: document RZ/T2H and RZ/N2H

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs include a
Temperature Sensor Unit (TSU). The device provides real-time temperature
measurements for thermal management, utilizing a single dedicated
channel for temperature sensing.
