ASoC: cs35l56: Move shared data into a common data structure

The ASoC and HDA drivers have structures that contain some of the same
information - instead of maintaining two locations for this data the
drivers should share a common data structure as this will enable common
utility functions to be created.

The first step is to move the location of these members in the ASoC
driver.
