sm8550/ayaneo: add displayport audio support

[xzn]

Summary

Enable displayport audio on ayaneo devices on sm8550.

Testing

Not tested with a full clean build, just copied the components onto an overlay on the device and tested that way. Tested on Ayaneo Pocket DS only.

Additional Context

Only tested on Pocket DS, I merely assume other Ayaneo sm8550 devcies work the same. Will need some testing from those who have other devices first!

• Reverse data-lanes spec is removed since displayport won't work on Pocket DS otherwise, not sure if it's the same way on other sm8550 Ayaneo devices.
• Removed data-lanes lane count limit since full 4 lanes works perfectly fine on Pocket DS.
• The updated tplg.bin file has source SM8550-APS.zip, you guys may be able to slim it down a little, I'm not experienced with it.
• Important currently the kernel doesn't have support for dsc for qualcomm displayport output, so if you test on a 4K screen it may fail anyway. Also there exist a qualcomm driver bug causing gamescope failing to output to external screen, those are separate issues.
