regulator: max8973: Let core handle GPIO descriptor
The probe path of this driver is a bit complex: sometimes the GPIO descriptor is passed to the regulator core, sometimes it is not. To handle it in a simple way: stick with the devm_* resource management and unhinge the GPIO descriptor devres handling right before passing it to the regulator core, if we pass it to the regulator core.
