So like what Marcel wrote over in his email, but with regulator vs.
GPIO. Seems completely reasonable for the BT HCI driver to support
that, if you ask me.

And indeed, that would get rid of the need for anything rfkill.

Sounds good to me, even if I have no idea (and don't really need to
know) what all that is :)

I'll look at killing the rfkill-regulator driver entirely though,
since, afaict, nothing uses it.
