ARM: dts: renesas: r9a06g032-rzn1d400-db: Drop invalid #cells properties

The 'ethernet-ports' node in the SoC DTSI handles them already. Fixes:

    arch/arm/boot/dts/renesas/r9a06g032-rzn1d400-db.dtb: switch@44050000 (renesas,r9a06g032-a5psw): Unevaluated properties are not allowed ('#address-cells', '#size-cells' were unexpected)
	    from schema $id: http://devicetree.org/schemas/net/dsa/renesas,rzn1-a5psw.yaml#

Fixes: 5b6d7c3c5861ad4a ("ARM: dts: r9a06g032-rzn1d400-db: Add switch description")
