I think it would be better to do an enable as opposed to removing the code.

This would be needed especially in applications that have to meet strict 
power management requirements.

Users may want to disable or enable the regulator during suspend/resume. 
Otherwise it would be considered always-on and the regulator does not 
need to be populated.
