regcache: Warn if regcache_sync() is called in cache_only mode
Calling regcache_sync() while cache_only is enabled is invalid API
usage, since writes are intentionally kept in the cache and cannot
be synchronized to hardware.
Document that callers must disable cache_only before calling
regcache_sync(), and reject incorrect usage with a WARN_ON() and
-EINVAL.
