The Renesas RZ/V2H SoC includes a Thermal Sensor Unit (TSU) block designed
to measure the junction temperature. The device provides real-time
temperature measurements for thermal management, utilizing two dedicated
channels for temperature sensing.

The Renesas RZ/V2H SoC is using the same TSU IP found on the RZ/G3E SoC,
the only difference being that it has two channels instead of one.

Add new compatible string "renesas,r9a09g057-tsu" for RZ/V2H and use
"renesas,r9a09g047-tsu" as a fallback compatible to indicate hardware
compatibility with the RZ/G3E implementation.
