ANDROID: GKI: regulator: Call proxy-consumer functions for each regulator registered

Browse Source 
Add a call to regulator_proxy_consumer_register() at the end of
regulator_register() and a call to
regulator_proxy_consumer_unregister() at the beginning of
regulator_unregister().  These calls ensure that proxy consumer
features may be used by any type of regulator regardless of the
driver supporting it.
