I needed a callback and added such. The callback was called on each DT
node parsed. However I dropped that idea because it turned our to be
unsuitable to my case.

I needed to feed regulator_config.ena_gpio with data parsed from such
callback. But the callback called from inside the regulator_register()
has the regulator_config const.
