Yaah, this is something new and I think Mark also wanted to do this cleanup
on his comment. I did not understand it previously. Looks cool now.

I did, please don't just ignore review comments.

However, I have requirement to configure PMIC with some inital setting based
on init_data (parsed) before regulator registration happened. Once I move to
this new mecahinsm, the inti_data parsing and regulator init happen in the
same function. So I need to have one callback from regulator_register to
driver.
Something below. This will do the pre configuration before
regulator_register happena dn machine constraint sets.

I can not use the init_data->regulator_init() as I need to have the init
data passed to the driver.

Why do you have this requirement?
