bangkk: Powerup and initialize sensor early [3/4]

Browse source 
Powering on and initializing main sensor in camera open instead of
streams configuration to optimize the startup KPI.
  It is a common feature and depends on sensor setting.
  It can save about 30ms.
Porting this func from (CR) and (CR).
