This is pretty much OK, just...

Now you're using the regulator init stuff to set the voltages you should
be able to drop most of the deviceless supplies.  I'd expect that you'd
want to keep the CPU core supplies for cpufreq support but the others
shouldn't need to be defined.  The names can be set in the constraints
- if set there they will be displayed to user space which normally makes
the diagnostics easier to follow for board users.
