dt-bindings: iommu: add new compatible strings 



The Allwinner H616 and A523 contain IOMMU IP very similar to the H6, but
use a different reset value for the bypass register, which makes them
strictly speaking incompatible.

Add a new compatible string for the H616, and a version for the A523,
falling back to the H616.
