[PATCH v2 2/2] soc: qcom: pmic_glink: notify clients about the current state

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

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.
