dt-bindings: can: renesas,rcar-canfd: Fix number of channels for R-Car V3U
According to the bindings, only two channels are supported. However, R-Car V3U supports eight, leading to "make dtbs" failures: arch/arm64/boot/dts/renesas/r8a779a0-falcon.dtb: can@e6660000: Unevaluated properties are not allowed ('channel2', 'channel3', 'channel4', 'channel5', 'channel6', 'channel7' were unexpected) Update the number of channels to 8 on R-Car V3U. While at it, prevent adding more properties to the channel nodes, as they must contain no other properties than a status property.
