arm64: dts: allwinner: Transpeed 8K618-T: add WiFi nodes
In contrast to other devices using Allwinner SoCs, the Transpeed 8K618-T
TV box uses a mainline supported WiFi chip: it's Broadcom 4335 compatible,
packaged by Murata.
Add the required DT nodes to let DT users know about the SDIO device.
There is an otherwise empty MMC device node, to receive the MAC address,
that firmware might want to write in there.
