ASoC: codecs: Remove unused reg_cache fields from device structs

The multi-component patch(commit f0fba2a) moved the allocation of the register cache from the driver to the ASoC core. Most drivers where adjusted to this, but there are quite a few drivers left which now have an unused reg_cache field in their private device struct. This patch removes these unused fields.
