fix the following dtc build warnings:

arch/arm/dts/o4-imx-nano.dtb: Warning (reg_format): /leds/led@0:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
...
arch/arm/dts/o4-imx-nano.dtb: Warning (avoid_default_addr_size): /leds/led@0: Relying on default #address-cells value
