No it is an explicitly defined SDIO device so we can add ethernet alias 
for it so we can for example set the MAC address of it via u-boot and etc :)

The actual driver for it is out of tree and from the current state of it

Orange Pi Zero Plus based on H5 does this exact thing as well for the 
same purpose with the same wifi chip :)
