Now that all users have been converted to regmap and the config.reg_bits and config.val_bits can be setted by each user through regmap core API. So these two params are redundant here.

Actually, I think the way to fix the issue with CODECs doing I/O in probe is to provide a way for drivers to specify a regmap when registering the CODEC (rather than during probe) and then move the initialisation of the regmap before the probe function is called. That would make set_cache_io() go away entirely.
