For regulators that are not turned on by bootloader, and which require

regulator when using dt?

If the regulator isn't software managed then always_on covers this - the
regulator core will enable any always_on regulators that haven't been
enabled already.

I'm not sure I understand the intended logic there.  Voltage constraints
and enable/disable constraints are orthogonal here.
