[PATCH] ARM: dts: imx: add proper #address-cells/#size-cells for ipu_di port nodes

[Shawn Guo]

It adds proper #address-cells/#size-cells for ipu_di port nodes to fix
the following DTC warnings.

arch/arm/boot/dts/imx6dl-aristainetos_7.dtb: Warning (reg_format): /soc/ipu at 2400000/port at 2/endpoint at 0:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
arch/arm/boot/dts/imx6dl-aristainetos_7.dtb: Warning (pci_device_bus_num): Failed prerequisite 'reg_format'
arch/arm/boot/dts/imx6dl-aristainetos_7.dtb: Warning (simple_bus_reg): Failed prerequisite 'reg_format'
arch/arm/boot/dts/imx6dl-aristainetos_7.dtb: Warning (avoid_default_addr_size): /soc/ipu at 2400000/port at 2/endpoint at 0: Relying on default #address-cells value
...
