DO NOT MERGE ANYWHERE implement wakelocks on bt adapter init

Implement wakelocks on bt adapter initialization. This fixes
an issue where the system enters suspend mode while bluetooth
device is initializing. This causes a watchdog time out. Fix
is to acquire a wakelock during this period to avoid entering
suspend mode.
