I have a suspicion that this will totally break my code.

That won't work either.  For one thing, the CS4270 driver registers
only one DAI, and it's called "cs4270-hifi".  So I have to call it
"cs4270-hifi".  So I can't call it anything else.

ASoC should detect when the machine driver is registering a connection
between a CPU object and a codec, if the codec's DAI has already been
given a sysfs entry.
