regulator: da9211: Hand over GPIO to regulator core
The GPIO descriptors used by the DA9211 driver are retrieved during probe() and it is really helpful to have those under devres management because of all the errorpaths in the intialization. Using the new dev_gpiod_unhinge() call we can remove the devres management of the descriptor right before handing it over to the regulators core.
