ASoC: core: Fix check before defaulting to regmap
Check if the chip has provided a write operation (which is mandatory for I/O) rather than looking for control data as some of the MFDs use a global for this. Also skip the attempt if there's no regmap available by device in case things get confused by the attempt to default.
