At first I didn't really like the callback, but it grew on me and I
realized why I didn't like it is because it's confusing that the
callback is called .choices() as well as the implementation used is
called .choices.
If anything it should be "set_choices" or "probe" with a slight leaning
on probe()..
With probe the flow could be:
driver()
->platform_profile_register(ops)
->->drivers's implementation for platform_profile_probe()
