The Allwinner A523 uses the same MMC IP as the D1. Introduce the new specific compatible strings, and use them with fallbacks to the D1 strings. Also it turned out that the A100 is not compatible to the H616, instead it is the same as the D1. For compatibility we cannot change the fallback chain, but any drivers are from now on supposed to match on the H616 string directly. Mark this fallback chain as deprecated, to avoid new users to be added.
