ARM: boards: skov-imx6: fix device tree path of state node

The reference broke in commit [1] and led to the following error message during
boot while fixing up the kernel devicetree:

  Loading ARM Linux zImage '/mnt/nand0.firmware.ubi.system0//boot/zImage'
  Loading devicetree from '/mnt/nand0.firmware.ubi.system0//boot/imx6dl-skov-revc-lt2.dtb'
  ERROR: skov-imx6 machine: Node /state/ethaddr/eth2 defining the state variable not found.
