SnapdragonCamera: Synchronize af & ae states before capturing
When in dual camera mode, synchronize AF and AE states between the two cameras before issuing capture requests. This allows capture requests to be issued simultaneously and achieves better temporal matching. CRs-Fixed: 993611 Change-Id: I097eae6b95153eefebeed3b22e02d4f4e56d565e
