Remove the compatible property from the list of required properties and
mark it as optional.

Changes in v2:
- Instead of moving the compatible string to the other binding, just
make it
    optional (remove from required list).

If you remove it from here then it's still required in Documentation/
devicetree/bindings/mmc/amlogic,meson-mx-sdio.yaml
so please add it.

If moving the compatible to its specific binding isn't appropriate (as
per Conor),
and if removing it from the required list here doesn’t seem reasonable
to you,
then adding an unnecessary compatible string in our DTS files doesn’t
make sense to me.

What could be the solution then?

The solution is right but you modify the meson-mx-sdio bindings, so
simply add compatible in a required list for the slot node.

Something like:

Conor, Is it right ?
