Please use a label based syntax here too.

The compatibility with the A13 has never been true, and the compatible
should be "allwinner,sun50i-h5-mmc", "allwinner,sun50i-a64-mmc".

And this is very likely to use the emmc compatible.

If it doesn't have the same clocks, it's not compatible with the H3.
