soc: qcom: pmic_glink: Use SERVREG_NOTIF_SERVICE_STATE_DOWN_V01 for PDR 



Currently, SERVREG_NOTIF_SERVICE_STATE_EARLY_DOWN_V01 event from
service-notifier is used to notify the clients to clean their
state during a PDR. However, this event is not being sent by
the remote subsystem unless PD dump is enabled. Also it is
recommended to use SERVREG_NOTIF_SERVICE_STATE_DOWN_V01 when a PD
state is actually down. Switch to use this instead.
