Add DisplayPort audio support for Xilinx ZynqMP platforms.
The current DT is, for some reason, missing the DMA channels for the
audio. This series adds that to the bindings and the dts file, but to
support older dtb files without the audio DMA, the driver will not fail
if the audio DMA is missing, but will just mark the audio support as
disabled.
