    ARM: dts: vf610: Fix pca9548 i2c-mux node names
    
    [ Upstream commit 42825d1f269355d63554ab3c3762611e4d8053e9 ]
    
    "make dtbs_check":
    
        arch/arm/boot/dts/vf610-zii-dev-rev-b.dtb: tca9548@70: $nodename:0: 'tca9548@70' does not match '^(i2c-?)?mux'
                From schema: Documentation/devicetree/bindings/i2c/i2c-mux-pca954x.yaml
        arch/arm/boot/dts/vf610-zii-dev-rev-b.dtb: tca9548@70: Unevaluated properties are not allowed ('#address-cells', '#size-cells', 'i2c@0', 'i2c@1', 'i2c@2', 'i2c@3', 'i2c@4' were unexpected)
                From schema: /scratch/geert/linux/linux-renesas/Documentation/devicetree/bindings/i2c/i2c-mux-pca954x.yaml
        ...
    
    Fix this by renaming PCA9548 nodes to "i2c-mux", to match the I2C bus
    multiplexer/switch DT bindings and the Generic Names Recommendation in
    the Devicetree Specification.
