Revert "Register both SMS-B and CB channels to support LTE"

This reverts commit cba619c3e8f416683e7b8dc44af9a0e9145b2ad6.

The original change try to turn on cellbroadcast listening on both GSM and CDMA 
channels at that same time.Thus some unexpected cellbroadcast message come in. 
We plan to revert this change.
