The DP subsystem for ZynqMP support audio via two channels, and the DP
DMA has dma-engines for those channels. For some reason the DT binding
has not specified those channels, even if the picture included in
xlnx,zynqmp-dpsub.yaml shows "2 x aud" DMAs.

Add the two audio DMAs to the binding.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
