I have only board with eMMC but I imagine it's the former. Even so, current approach with Allwinner boards is to have two different board DT files, one for each variant. This can be seen from Documentation/devicetree/bindings/arm/ sunxi.yaml which has a lot of compatibles ending with "-emmc". I guess reason for that is to avoid having MMC controller being powered on for no reason.
Best regards, Jernej
