soc: qcom: Register for indication cb after obtaining state of remote pd

This change moves the registration of indication call back after inquiring
the state of remote PD, this is logical flow since in any case just after
registration we are inquiring the state and doing client notification.

With existing arrangement of code, sometime there is occurring a race
condition between inquiring the remote pd state and indication call back.
