soc: qcom: pmic_glink: notify clients about the current state
[ Upstream commit d6cbce2cd354c9a37a558f290a8f1dfd20584f99 ]
In case the client is registered after the pmic-glink recived a response
from the Protection Domain mapper, it is going to miss the notification
about the state. Notify clients about the current state upon
registration.
