Bluetooth: Disable bluetooth only if BT Sevice is connected

Bluetooth service is imidiately disconnected from the adapter
after SSR OR if any bluetooth services is crashed OR framework
is crashed. As Bluetooth  service is not connected OR Bluetooth
is not enabled, So BT disable should be ignored & bluetooth
persist setting should not be changed.

platform: Remove mapping of android.permission.CAMERA to camera group

This mapping introduces security risk where any app with android.
permission.CAMERA can open camera driver directly without going
through mediaserver.
