[PATCH] arm64: dts: renesas: Fix thermal-sensors on single-zone sensors

[Geert Uytterhoeven]

    arch/arm64/boot/dts/renesas/r8a77990-ebisu.dtb: thermal-zones: cpu-thermal:thermal-sensors: [[105], [0]] is too long
	    From schema: Documentation/devicetree/bindings/thermal/thermal-zones.yaml

Indeed, the thermal sensors on R-Car E3 and RZ/G2E support only a single
zone, hence #thermal-sensor-cells = <0>.

Fix this by dropping the bogus zero cell from the thermal sensor
specifiers.
