I don't think it is a required property for the dw-mmc itself, as only
in special-cases do you need subnodes there. Like emmc and sd-cards
are completely probeable without needing further information and
only the wifi/bt chips _might_ need these.

So I don't think that this is a property of the controller itself, but te
connected card - hence should stay in the board file.
