Subject: [PATCH v2 6/7] ARM: dts: ls1021a-tsn: Remove redundant
 #address-cells for ethernet-switch@1

Remove redundant #address-cells and #size-cells for ethernet-switch@1
because children node have not address.

Fix below CHECK_DTBS warnings:
  arch/arm/boot/dts/nxp/ls/ls1021a-tsn.dtb: ethernet-switch@1 (nxp,sja1105t): Unevaluated properties are not allowed ('#address-cells', '#size-cells' were unexpected)
	from schema $id: http://devicetree.org/schemas/net/dsa/nxp,sja1105.yaml#
