ASoC: Remove snd_soc_cache_sync() implementation

Browse Source 
This function has no more non regmap user, which means we can remove the
implementation of the function and associated functions and structure
fields.

For convenience we keep a static inline version of the function that
forwards calls to regcache_sync() unconditionally.
