arm64: dts: marvell: espressobin-ultra: fix Ethernet Switch unit address
The Espressobin Ultra DTS includes Espressobin DTSI which defines ethernet-switch@1 node. The Ultra DTS overrides "reg" to 3, but that leaves still old unit address which conflicts with the new phy@1 node (W=1 dtc warning): armada-3720-espressobin.dtsi:148.29-203.4: Warning (unique_unit_address_if_enabled): /soc/internal-regs@d0000000/mdio@32004/ethernet-switch@1: duplicate unit-address (also used in node /soc/internal-regs@d0000000/mdio@32004/ethernet-phy@1) Fix this by deleting ethernet-switch@1 node and merging original node with code from Ultra DTS into new ethernet-switch@3.
