actually I do think you might just want to add address+size-cells
to your &sdio0 instance instead. Especially as I'm not sure that the
system will find the card-node when matching against the card itself
without the reg property?
The core sdio0 does not necessarily have subnodes, so I guess
the *-cells may just live in the board dts?
