Please check below comments from Thomas Abraham and I agree with his
opinion.

There cannot be a node that represents a virtual device. Device tree should
ideally describe the hardware but the above node does not represent a
hardware device. The creation of the platform device instance for the above
device should handled inside the kernel code.

Thanks.
