While I agree with this observation, the suggested naming does not
reflect the rationale of CPU0 though, which is really important for
driver to work, and is exactly the thing I like about *_CPU0 naming.

The driver needs the following stuff around CPU0 to be functional.

- Device tree node /cpus/cpu at 0
- clk lookup with dev_id being "cpu0"
- regulator with id being "cpu0"

I think the *_CPU0 naming does a better job on emphasising those in the
first place.
