ASoC: ep93xx: get rid of ep93xx-pcm-audio struct device
Modify the ep93xx PCM driver so that it's a utility library that can be registered on each DAI, rather than a separate struct device. This is more in line with how many recent DT-converted platforms operate, and avoids the need for yet another struct device.
