[PATCH 02/14] dt-bindings: mmc: sunxi: add compatible strings for Allwinner A523

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.
