[PATCH 0/4] Get optimal audio frequency and channels

[Mitul Golani]

Obtain the optimal audio rate and channel based on available display
timing constraints.

This can be achieved by:
- Adding DRM wrappers to retrieve the supported channel and rate
information from SADs.
- Adding audio-related config parameters in the CRTC state, such
as audio support, rate, and channel.
- Initializing the audio config parameters with the maximum supported
rate and channel by the audio source.
- Computing the SADs based on the audio source's capabilities.
