ASoC: pcm512x: Rearrange operations in `hw_params()`
This commit is a preparation for the next patch in the series. It's goal is to make format check easy-to-move-out. Theoretically, more butifications are possile in `hw_params()` func, but my intention in this commit is to keep behaviour unchanged.
