Support multiple SIM/Subscription on telephony registration

During calling telephony registry call back API, we force the call back will be
triggered if the registered subId is Default Sub ID. This is due to some risk
condition. Please refer to Issue 17472622 and its fix. This fix is ok for single
SIM/Subscription. However, on multiple SIM/subscription, there is potential problem
on wrong notifications.
