Currently the checking for if a component sits on the CPU or CODEC side of the DAI link is done with a helper function that checks if the component defines legacy_dai_naming. However, there are already a couple of CPU side components that explicitly opt in to non-legacy DAI naming and it doesn't seem like a very robust solution. Rather than looking for the flag check if the component is attached to any of the CODEC DAIs on the DAI link. This is more robust and helps to bring the core further in the direction of a component being a generic block rather than being classified as platform or CODEC drivers.
