Subject: [PATCH 1/3] arm64: dts: marvell: eDPU: drop redundant address/size-cells

The ethernet-switch node does not have children with unit addresses, so
address/size-cells are not really correct, as reported by dtc W=1
warning:

  armada-3720-eDPU.dts:26.19-60.4: Warning (avoid_unnecessary_addr_size): /soc/internal-regs@...00000/mdio@...04/switch@0: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

This probably also fixes dtbs_check warning, but I could not find it, so
not sure about that.
