I think the best solution would be to parse the "/aliases" device node
and look for an "mmc0" or "mmc1" property with a phandle to the respective
device. That's how we sort the serial ports. We have the of_alias_get_id()
function to pick out a node from there, so it should be possible to use
that in the mmc core similar to how we use it in the uart drivers.
