vdd supply will be automatically disabled on error condition during a
probe and on driver cleanup. Since the vdd handling is moved to
devm-helpers, only vddio regulator has to be disabled in the
driver-specific cleanup action.

You can rename now _data --> st...

I'm not that expert in regulator framework, but this change might be sensitive.
I dunno if regulator is exclusive or shared and if order of requesting may affect
anything. Just needs careful review from somebody more familiar with that.
