OK, that's fine - it's setting things outside the normal API flow which
is all that I was asking.

That'd be a boot_off constraint if someone requires it.  So far nobody
has - there's not going to be many cases where it's appropriate to do
so, normally either you want to leave the supplies on for the device
driver that's taking control of the device or it does no harm to wait
till the end of init.
